Question 1Physical Geography (Geomorphology, Climatology, Oceanography)

Which layer of the Earth's interior is believed to be in a liquid state, as inferred from the behaviour of seismic S-waves?

  1. The outer core Correct answer.
  2. The asthenosphere
  3. The lower mantle
  4. The inner core

Explanation

S-waves cannot pass through liquids, and their disappearance beyond a certain depth indicates a liquid zone. This zone is the outer core, which lies between the mantle and the solid inner core.

Question 2Physical Geography (Geomorphology, Climatology, Oceanography)

A river flowing across a gently sloping plain repeatedly shifts its channel, leaving behind a broad belt of former meanders. This feature is best described as

  1. A flood plain made of meander scars Correct answer.
  2. A gorge cut by vertical erosion
  3. A levee raised along the banks
  4. A delta built at a river mouth

Explanation

Lateral migration of meanders over a low-gradient plain abandons old curves, which remain as arc-shaped scars on the flood plain. The resulting belt of abandoned channels is a characteristic flood-plain feature of mature rivers.

Question 3Physical Geography (Geomorphology, Climatology, Oceanography)

Which process of mass movement involves the slow, imperceptible downslope creep of soil on a hillside, often revealed by tilted fence posts?

  1. Mudflow
  2. Slump
  3. Soil creep Correct answer.
  4. Rockfall

Explanation

Soil creep is an extremely slow, continuous downslope movement driven by gravity and wetting-drying cycles. Because it is gradual, it is detected through bent or tilted objects such as fence posts and trees.

Question 4Physical Geography (Geomorphology, Climatology, Oceanography)

In the troposphere, temperature normally decreases with increasing altitude. What is the primary reason for this decrease?

  1. Ozone absorbs ultraviolet radiation at these heights
  2. The pressure of the air rises steadily with altitude
  3. Charged particles from the Sun heat the upper layers
  4. The troposphere is heated mainly from the Earth's surface below Correct answer.

Explanation

The troposphere is heated largely by terrestrial radiation and by conduction from the warmed ground, so temperature falls with height away from this heat source. This is why the lapse rate is positive in the troposphere.

Question 5Physical Geography (Geomorphology, Climatology, Oceanography)

Which type of rainfall occurs when moist air is forced to rise over a mountain barrier, cooling and condensing on the windward slope?

  1. Orographic rainfall Correct answer.
  2. Cyclonic rainfall
  3. Frontal rainfall
  4. Convectional rainfall

Explanation

Orographic rainfall results when relief forces moist air to ascend a slope, causing adiabatic cooling and condensation. The leeward side then receives little rain and forms a rain-shadow.

Question 6Physical Geography (Geomorphology, Climatology, Oceanography)

The Coriolis effect deflects freely moving air. In the Southern Hemisphere, the deflection of winds is

  1. Zero at all latitudes
  2. Always directly toward the equator
  3. To the right of their direction of motion
  4. To the left of their direction of motion Correct answer.

Explanation

Because of the Earth's rotation, moving air appears deflected to the left in the Southern Hemisphere and to the right in the Northern Hemisphere. The deflection grows with latitude and is zero at the equator.

Question 7Physical Geography (Geomorphology, Climatology, Oceanography)

Which ocean current is a warm current that flows northward along the eastern coast of North America?

  1. The California Current
  2. The Gulf Stream Correct answer.
  3. The Canary Current
  4. The Labrador Current

Explanation

The Gulf Stream carries warm tropical water northward along the eastern seaboard of North America before crossing the Atlantic. Its warmth moderates the climate of adjoining coasts.

Question 8Physical Geography (Geomorphology, Climatology, Oceanography)

Which of the following is the most common chemical constituent of sea water by mass?

  1. Potassium bromide
  2. Calcium carbonate
  3. Magnesium sulphate
  4. Sodium chloride Correct answer.

Explanation

Sodium chloride is the dominant dissolved salt in sea water, accounting for the greater part of its salinity. Other salts such as magnesium and calcium compounds occur in much smaller amounts.

Question 9Physical Geography (Geomorphology, Climatology, Oceanography)

A stream flows from a steep mountain valley onto a flat plain, where it suddenly spreads its load in a fan shape. This landform is called

  1. A point bar
  2. An oxbow lake
  3. A plunge pool
  4. An alluvial fan Correct answer.

Explanation

When a steep-gradient stream loses velocity on reaching flatter ground, it deposits coarse sediment in a fan-shaped spread. This depositional feature is an alluvial fan.

Question 10Physical Geography (Geomorphology, Climatology, Oceanography)

Limestone country shows sinkholes, swallow holes and underground streams. Which weathering process is chiefly responsible for these features?

  1. Frost shattering of rock
  2. Chemical solution by carbonic acid Correct answer.
  3. Exfoliation by heating and cooling
  4. Abrasion by wind-blown sand

Explanation

Rain water charged with carbon dioxide forms weak carbonic acid, which dissolves calcium carbonate in limestone. This chemical solution creates karst features such as sinkholes and subterranean drainage.

Question 11Physical Geography (Geomorphology, Climatology, Oceanography)

Which of the following conditions would most favour the formation of a glacier on a high mountain?

  1. Steep slopes that shed snow rapidly into the valley
  2. High summer temperatures that melt all winter snow each year
  3. Low precipitation with strong evaporation throughout the year
  4. Heavy snowfall with summers too cool to melt the accumulated snow Correct answer.

Explanation

Glaciers form where accumulation of snow exceeds ablation over many years. Cool summers and abundant snowfall allow snow to persist and compact into ice.

Question 12Physical Geography (Geomorphology, Climatology, Oceanography)

Winds blow from a high-pressure cell toward a low-pressure cell, but do not move directly along the pressure gradient. The main reason they follow a curved path is

  1. Friction with the Earth's surface
  2. The gravitational pull of the Moon
  3. The Coriolis effect due to the Earth's rotation Correct answer.
  4. The pressure gradient force

Explanation

The pressure gradient force starts air moving, but the Earth's rotation deflects the moving air, producing curved paths. Friction slows the wind but does not create the deflection.

Question 13Physical Geography (Geomorphology, Climatology, Oceanography)

During a strong El Nino year, which change is typically observed in the equatorial Pacific?

  1. A permanent rise in salinity of the western Pacific only
  2. Strengthening of the trade winds and cooling of the eastern Pacific
  3. Warming of surface water in the eastern Pacific and weakened trade winds Correct answer.
  4. Complete cessation of the Walker circulation with no climatic effect

Explanation

El Nino involves anomalous warming of the eastern equatorial Pacific and a weakening of the normal trade winds. This disrupts the Walker circulation and affects rainfall patterns across the Pacific region.

Question 14Physical Geography (Geomorphology, Climatology, Oceanography)

A deep ocean trench is most likely to be found

  1. Over a broad continental shelf
  2. At the centre of a mid-oceanic ridge
  3. Along a convergent boundary where an oceanic plate subducts Correct answer.
  4. Along a transform fault where plates slide past each other

Explanation

Trenches are formed where one lithospheric plate descends beneath another at a convergent margin. The down-bending slab creates the deep, narrow depression.

Question 15Physical Geography (Geomorphology, Climatology, Oceanography)

Which sequence correctly shows the increasing intensity of the three main types of earthquake waves in terms of their destructive capacity at the surface?

  1. S-waves, P-waves, surface waves
  2. Surface waves, S-waves, P-waves
  3. P-waves, S-waves, surface waves Correct answer.
  4. P-waves, surface waves, S-waves

Explanation

P-waves arrive first but cause the least damage; S-waves follow with stronger shaking; surface waves travel slowest but produce the greatest ground displacement and destruction. Hence the order of increasing destructiveness is P, S, surface.

Question 16Physical Geography (Geomorphology, Climatology, Oceanography)

A coastal area experiences two high tides and two low tides of nearly equal height each day. This tidal pattern is described as

  1. Semi-diurnal tides Correct answer.
  2. Mixed tides
  3. Diurnal tides
  4. Spring tides only

Explanation

Semi-diurnal tides show two highs and two lows of similar range within about a lunar day. This pattern is typical of many open coasts facing the ocean.

Question 17Physical Geography (Geomorphology, Climatology, Oceanography)

Which of the following best explains why coastal deserts such as the Atacama occur beside the ocean?

  1. The Coriolis effect prevents any clouds from forming
  2. Warm currents supply abundant moisture that falls as rain
  3. Mountain barriers block all moisture from reaching the coast
  4. Cold offshore currents cool the air and inhibit condensation and rainfall Correct answer.

Explanation

Cold currents chill the air above them, making it stable and reducing its capacity to rise and condense, so rainfall is suppressed. The Atacama lies beside the cold Peru Current, which helps keep it arid.

Question 18Physical Geography (Geomorphology, Climatology, Oceanography)

A rock mass moves downslope along a curved, concave-up surface, rotating backward as it goes. This type of mass movement is

  1. A lahar
  2. A slump Correct answer.
  3. A debris avalanche
  4. A rockfall

Explanation

A slump is a rotational slide in which material moves along a curved failure plane, tilting backward. It is common on steep, water-saturated slopes.

Question 19Physical Geography (Geomorphology, Climatology, Oceanography)

Which of the following statements about the relationship between pressure gradient and wind speed is correct?

  1. Wind speed depends only on temperature, not pressure
  2. Wind speed is independent of the pressure gradient
  3. A steeper pressure gradient produces faster winds Correct answer.
  4. A gentler pressure gradient produces faster winds

Explanation

The pressure gradient force is proportional to the rate of pressure change over distance, so closely spaced isobars indicate strong winds. Widely spaced isobars indicate gentle gradients and light winds.

Question 20Physical Geography (Geomorphology, Climatology, Oceanography)

Which landform is produced by the deposition of till and outwash at the farthest point reached by an advancing glacier?

  1. A cirque
  2. A terminal moraine Correct answer.
  3. A hanging valley
  4. A roche moutonnee

Explanation

A terminal moraine marks the maximum extent of a glacier and consists of debris deposited at its snout. It forms a ridge across the valley at the ice front.

Question 21Physical Geography (Geomorphology, Climatology, Oceanography)

The Himalayan range continues to rise because the Indian plate is converging with the Eurasian plate. Which tectonic setting does this represent?

  1. A transform boundary between two continents
  2. A continent-continent convergent boundary Correct answer.
  3. A hot spot beneath a continental plate
  4. A divergent boundary within a continent

Explanation

Where two continental plates collide, neither subducts deeply and the crust is thickened and uplifted into fold mountains. The Himalayas are the classic example of such a collision.

Question 22Physical Geography (Geomorphology, Climatology, Oceanography)

In a region of strong insolation and clear skies, the daily temperature range between day and night is likely to be large. This is chiefly because

  1. Cloud cover traps heat both day and night
  2. Winds mix the air and equalise temperatures
  3. Clear skies allow rapid heating by day and rapid radiation loss by night Correct answer.
  4. Humidity is high enough to prevent cooling at night

Explanation

With clear skies, solar radiation reaches the ground unhindered by day, while at night terrestrial radiation escapes freely to space. The result is strong daytime heating and rapid nocturnal cooling, giving a wide diurnal range.

Question 23Physical Geography (Geomorphology, Climatology, Oceanography)

Ocean salinity is generally highest in the subtropical belts and lower near the equator and the poles. Which explanation best accounts for this pattern?

  1. High evaporation with low rainfall raises salinity in the subtropics, while heavy rain and ice melt dilute it elsewhere Correct answer.
  2. Salinity depends only on the age of the water mass
  3. Cold water always holds more dissolved salt than warm water
  4. River discharge is the sole control of ocean salinity

Explanation

Salinity reflects the balance between evaporation, which concentrates salts, and precipitation and meltwater, which dilute them. The subtropics combine strong evaporation with little rain, so salinity peaks there.

Question 24Physical Geography (Geomorphology, Climatology, Oceanography)

A river's discharge increases sharply downstream while its gradient falls. Which combination best explains the resulting channel form?

  1. Greater discharge always produces a straight channel with no deposition
  2. Lower gradient increases velocity and causes the channel to deepen by abrasion
  3. Greater discharge narrows the channel while the lower gradient increases vertical erosion
  4. Greater discharge widens and deepens the channel, while a lower gradient favours meandering and deposition Correct answer.

Explanation

Downstream, increasing discharge enlarges the channel cross-section, while the gentler gradient reduces stream power and encourages lateral migration and deposition. Meanders and flood plains therefore become typical of the lower course.

Question 25Physical Geography (Geomorphology, Climatology, Oceanography)

Two coastal stations lie at the same latitude, but one has a much smaller annual temperature range. Which factor most plausibly explains the difference?

  1. The higher altitude of the maritime station
  2. The greater distance of the maritime station from the equator
  3. The stronger Coriolis effect at the maritime station
  4. The moderating influence of a nearby ocean compared with a continental interior Correct answer.

Explanation

Water heats and cools more slowly than land, so maritime locations have cooler summers and milder winters, giving a small annual range. Continental interiors, far from this moderating influence, show a large range.

Question 26Physical Geography (Geomorphology, Climatology, Oceanography)

Which of the following best describes the process of chemical weathering known as carbonation in limestone regions?

  1. Water freezes in cracks and expands, prising the rock apart physically
  2. Plant roots penetrate joints and mechanically wedge the rock fragments apart
  3. Carbon dioxide dissolves in rainwater to form carbonic acid, which reacts with calcium carbonate and dissolves it Correct answer.
  4. Oxygen combines with iron minerals in the rock to form oxides that expand and flake off

Explanation

Carbonation is a chemical process in which carbon dioxide from the atmosphere and soil dissolves in rainwater, producing weak carbonic acid. This acid reacts with calcium carbonate in limestone, converting it into soluble calcium bicarbonate, which is carried away in solution. The result is the characteristic solution weathering of karst landscapes.

Question 27Physical Geography (Geomorphology, Climatology, Oceanography)

A broad, gently sloping accumulation of angular rock fragments is found at the foot of a steep cliff in a cold mountain area. Which process most directly produced this deposit?

  1. Repeated freeze-thaw action breaking rock and gravity moving the debris downslope Correct answer.
  2. Chemical solution of the cliff rock by carbonic acid and later precipitation
  3. Deposition of fine silt by wind deflation from the cliff face
  4. Deposition of glacial till carried and dumped by an advancing ice sheet

Explanation

In cold mountain environments, water enters joints in the cliff, freezes, and expands, shattering the rock into angular fragments. These fragments fall or creep downslope under gravity and gather as a talus or scree slope at the base. The angularity and position directly below the cliff distinguish this from water- or ice-transported deposits.

Question 28Physical Geography (Geomorphology, Climatology, Oceanography)

Which of the following is the correct order of layers in the Earth's interior, moving from the surface toward the centre?

  1. Crust, outer core, mantle, inner core
  2. Mantle, crust, inner core, outer core
  3. Crust, mantle, outer core, inner core Correct answer.
  4. Outer core, mantle, crust, inner core

Explanation

Seismic evidence shows the Earth is layered by composition and physical state. Beneath the thin crust lies the solid but slowly flowing mantle, then the liquid outer core, and finally the solid inner core. The order matters because the liquid outer core is responsible for generating the planet's magnetic field.

Question 29Physical Geography (Geomorphology, Climatology, Oceanography)

A river crosses a region of hard, resistant rock and then enters a band of softer rock. Which feature is most likely to develop at the boundary?

  1. A waterfall or rapids where the river cuts more rapidly into the weaker rock Correct answer.
  2. A delta at the point where the river leaves the hard rock
  3. A natural levee built along the banks of the hard rock section
  4. A wide floodplain of fine alluvium upstream of the hard rock band

Explanation

Where a river passes from resistant rock onto softer rock, differential erosion is concentrated on the weaker material. The softer band is worn down faster, creating a step in the long profile that appears as rapids or a waterfall. Over time this step retreats upstream as the hard caprock is undercut.

Question 30Physical Geography (Geomorphology, Climatology, Oceanography)

A scientist measures the temperature of the atmosphere at increasing altitude in the troposphere. Which statement correctly describes the normal pattern observed?

  1. Temperature rises steadily with altitude because the ozone layer absorbs ultraviolet radiation
  2. Temperature remains constant with altitude because the troposphere is well mixed by winds
  3. Temperature falls only above the tropopause, while the troposphere shows no clear trend
  4. Temperature falls with altitude because the troposphere is heated mainly from the Earth's surface below Correct answer.

Explanation

The troposphere is heated primarily from below, as the Earth's surface absorbs solar radiation and warms the air in contact with it. Air temperature therefore decreases with height in this layer at the environmental lapse rate. This is why high mountains remain cold even though they are closer to the sun.

Question 31Physical Geography (Geomorphology, Climatology, Oceanography)

An air mass forms over a warm tropical ocean and then moves over a cold ocean current. What is most likely to happen to the air mass?

  1. It loses all its moisture instantly and becomes a continental polar air mass
  2. It becomes more unstable and produces frequent thunderstorms
  3. It cools from below, becomes stable, and may produce fog or low stratus cloud Correct answer.
  4. It warms from below and gains additional water vapour

Explanation

When warm, humid air moves over a cold surface, the lowest layer is chilled while the air above remains warmer. This creates a temperature inversion that suppresses vertical motion, making the air stable. Moisture condenses as fog or low stratus rather than rising into showers.

Question 32Physical Geography (Geomorphology, Climatology, Oceanography)

Two places at the same latitude record different annual rainfall totals because one lies on a windward slope and the other on the leeward slope of a mountain range. Which mechanism explains this difference?

  1. The windward side is farther from the sea and therefore receives less moisture
  2. Orographic uplift causes cooling and condensation on the windward side, while the leeward side receives descending dry air Correct answer.
  3. Convectional heating is stronger on the leeward side, producing more afternoon showers there
  4. Frontal depressions stall on the leeward side and release their rain there

Explanation

Moist air forced to rise over a mountain range expands and cools, so its water vapour condenses and falls as rain on the windward slope. As the air descends the leeward side it warms and its relative humidity falls, producing a dry rain-shadow. This orographic effect explains why windward slopes are wetter than leeward ones at the same latitude.

Question 33Physical Geography (Geomorphology, Climatology, Oceanography)

Which of the following correctly describes the formation of a tropical cyclone?

  1. It forms over cold polar seas where dense air sinks rapidly and spins up a vortex
  2. It forms over warm ocean water above about 27 degrees Celsius, where latent heat released by condensation intensifies the low-pressure system Correct answer.
  3. It forms over land when strong daytime heating creates a local low that draws in dry air
  4. It forms along a frontal boundary between two cold air masses over a continent

Explanation

Tropical cyclones require a warm ocean surface that supplies heat and moisture to the air above. As the moist air rises, condensation releases latent heat, which warms the core and lowers pressure further, strengthening the circulation. This positive feedback explains why these storms form over warm tropical seas and weaken after landfall.

Question 34Physical Geography (Geomorphology, Climatology, Oceanography)

A deep-sea instrument records a sudden increase in the height of ocean water passing a coastal station, followed by a series of waves arriving over several hours after an offshore earthquake. Which phenomenon is being described?

  1. A spring tide caused by the alignment of the sun and moon
  2. A rip current caused by wave action on a beach
  3. A storm surge driven by strong onshore winds
  4. A tsunami generated by displacement of the sea floor Correct answer.

Explanation

An underwater earthquake can suddenly displace the sea floor, lifting or dropping a large volume of water and setting off a tsunami. The waves travel rapidly across the open ocean and grow in height as they enter shallow coastal water. The arrival of several waves over hours after the earthquake is characteristic of a tsunami.

Question 35Physical Geography (Geomorphology, Climatology, Oceanography)

In the open ocean, a surface current flows along a coast with the land to its left in the Northern Hemisphere. Which statement about the resulting coastal water is most accurate?

  1. Upwelling brings cold nutrient-rich water to the surface, supporting rich fisheries Correct answer.
  2. The current piles warm water against the coast and raises sea level permanently
  3. The current causes the sea surface to slope downward toward the coast, driving water offshore
  4. The current has no effect on coastal water temperature or nutrient supply

Explanation

When a surface current moves with the coast on its left in the Northern Hemisphere, Ekman transport pushes surface water offshore. Deeper, colder water then rises to replace it in a process called upwelling. This cold water carries nutrients that support productive fisheries along such coasts.

Question 36Physical Geography (Geomorphology, Climatology, Oceanography)

A layer of ocean water shows a rapid decrease in temperature with depth over a short vertical distance. What is this layer called, and what does it do to vertical mixing?

  1. The halocline, which resists mixing because of a sharp change in salinity
  2. The thermocline, which resists vertical mixing because warm water lies above cold, dense water Correct answer.
  3. The pycnocline, which promotes mixing because density decreases with depth
  4. The photic zone, which promotes mixing because sunlight warms the water evenly

Explanation

A thermocline is a zone of rapid temperature change with depth, separating warmer surface water from colder deep water. Because warm water is less dense than cold water, the layering is stable and resists vertical mixing. This stratification keeps nutrients in deep water separated from the sunlit surface layer.

Question 37Physical Geography (Geomorphology, Climatology, Oceanography)

A sample of sea water is evaporated and the residue is examined. Which statement about the composition of sea water is correct?

  1. Calcium carbonate is the dominant dissolved salt, with sodium chloride present only in trace amounts
  2. Dissolved gases such as oxygen form the largest part of the residue by mass
  3. Organic matter from marine organisms accounts for most of the dissolved solids
  4. Sodium chloride makes up most of the dissolved salt, with smaller amounts of magnesium, calcium and potassium salts Correct answer.

Explanation

About 85 percent of the dissolved salts in sea water consist of sodium chloride, which is why sea water tastes salty. Smaller but significant amounts of magnesium, calcium, potassium and sulphate salts are also present. Dissolved gases and organic matter form only a tiny fraction of the total dissolved solids.

Question 38Physical Geography (Geomorphology, Climatology, Oceanography)

A sedimentary rock sequence contains a layer of conglomerate with rounded pebbles overlain by a layer of fine shale. What does this change most likely indicate about the depositional environment?

  1. A glacial advance that deposited till over lake sediments
  2. A rise in energy, from a quiet lake to a fast-flowing mountain stream
  3. A period of intense chemical weathering that dissolved the pebbles
  4. A fall in energy, from a high-energy river or beach setting to a quiet, deep-water setting Correct answer.

Explanation

Coarse, rounded material such as conglomerate is deposited where energy is high enough to move large particles, as in rivers or beaches. Fine shale settles only where water is quiet, such as a deep lake or offshore basin. The upward change from coarse to fine therefore records decreasing energy, a pattern called a fining-upward sequence.

Question 39Physical Geography (Geomorphology, Climatology, Oceanography)

A region experiences a hot, dry summer and a mild, wet winter, with vegetation dominated by drought-resistant shrubs. Which climatic classification best fits this description?

  1. Tundra climate
  2. Tropical monsoon climate
  3. Mediterranean climate Correct answer.
  4. Humid continental climate

Explanation

A Mediterranean climate is characterised by dry, hot summers and mild, wet winters, driven by the seasonal shift of subtropical high-pressure and westerly wind belts. The dry summer forces vegetation to adapt with small, waxy or leathery leaves. This seasonal pattern of rainfall is the defining feature of the classification.

Question 40Physical Geography (Geomorphology, Climatology, Oceanography)

A plate boundary runs through an ocean basin, where new oceanic crust forms along a ridge and the sea floor spreads away from it on both sides. Which evidence would best support this model?

  1. Earthquake foci are deepest directly beneath the ridge axis
  2. Sediment thickness decreases away from the ridge on both sides
  3. The ocean floor is oldest at the ridge and becomes progressively younger outward
  4. The age of the ocean floor increases symmetrically with distance from the ridge on either side Correct answer.

Explanation

Sea-floor spreading predicts that new crust forms at the ridge and moves outward, so crust should be youngest at the ridge and older farther away. Matching magnetic stripes and increasing sediment thickness away from the ridge support this model. Symmetrical age patterns on both sides are among the strongest lines of evidence.

Question 41Human Geography (Population, Settlement, Economic Activities)

Which term describes the number of live births per 1000 people in a population in a given year?

  1. Natural increase rate
  2. Infant mortality rate
  3. Crude birth rate Correct answer.
  4. Crude death rate

Explanation

The crude birth rate expresses live births in a year per 1000 of the total mid-year population, without adjusting for age or sex structure. Death rate and infant mortality count deaths, while natural increase rate is the gap between births and deaths.

Question 42Human Geography (Population, Settlement, Economic Activities)

A country records a crude birth rate of 38 and a crude death rate of 12 per 1000. What is its annual rate of natural increase?

  1. 50 per cent
  2. 26 per cent
  3. 2.6 per cent Correct answer.
  4. 3.2 per cent

Explanation

Natural increase is birth rate minus death rate, giving 26 per 1000. Converting per 1000 to per cent means dividing by 10, so the rate is 2.6 per cent per year.

Question 43Human Geography (Population, Settlement, Economic Activities)

In the demographic transition model, which stage shows both high birth rates and high death rates with a nearly stable population?

  1. Stage two
  2. Stage three
  3. Stage one Correct answer.
  4. Stage four

Explanation

Stage one is the pre-industrial phase where birth and death rates are both high, so population growth is minimal. Later stages see death rates fall first, followed by declining birth rates.

Question 44Human Geography (Population, Settlement, Economic Activities)

Which pair of factors is best described as push factors in rural-to-urban migration?

  1. Better schools and hospital facilities
  2. Higher urban wages and factory jobs
  3. Farm mechanisation and land fragmentation Correct answer.
  4. Improved transport and market access

Explanation

Push factors drive people away from a place of origin, such as mechanisation reducing farm labour demand and fragmented holdings that cannot support a family. The other options are attractions at the destination, which are pull factors.

Question 45Human Geography (Population, Settlement, Economic Activities)

A settlement pattern in which houses are strung along a single road or river valley is called

  1. Nucleated settlement
  2. Linear settlement Correct answer.
  3. Dispersed settlement
  4. Circular settlement

Explanation

Linear settlements develop along a line of movement or a water source, so dwellings follow the road or valley. Dispersed settlement scatters isolated farms, and nucleated settlement clusters houses around a focus such as a market or crossroads.

Question 46Human Geography (Population, Settlement, Economic Activities)

Which function most typically explains the origin of a nucleated settlement at a crossroads in a fertile plain?

  1. Pilgrimage to a remote shrine
  2. Mining of deep mineral seams
  3. Defence against coastal raids
  4. Collection and exchange of agricultural surplus Correct answer.

Explanation

Crossroads in productive farmland become market and service nodes where surrounding farmers bring surplus for exchange, attracting permanent buildings. Defence, mining and pilgrimage explain other settlement origins but not the crossroads-in-farmland case.

Question 47Human Geography (Population, Settlement, Economic Activities)

According to the concentric zone model of urban structure, which zone lies immediately outside the central business district?

  1. Zone of workingmen's homes
  2. Zone of transition Correct answer.
  3. Residential zone
  4. Commuter zone

Explanation

The zone of transition surrounds the CBD and mixes older housing with light industry and commerce, often showing decay and invasion by CBD functions. Outer zones are successively residential and then commuter settlements.

Question 48Human Geography (Population, Settlement, Economic Activities)

Which of these is a primary economic activity?

  1. Software design
  2. Fishing Correct answer.
  3. Flour milling
  4. Insurance

Explanation

Primary activities directly extract resources from nature, and fishing is the harvesting of wild aquatic resources. Milling, insurance and software are secondary, tertiary and quaternary activities respectively.

Question 49Human Geography (Population, Settlement, Economic Activities)

A country exports raw cotton and imports finished cloth. Which change in its trade structure would indicate industrial upgrading?

  1. Exporting more raw cotton and importing more cloth
  2. Increasing raw cotton exports while cutting cloth imports
  3. Replacing cotton with another raw fibre for export
  4. Exporting yarn and garments instead of raw cotton Correct answer.

Explanation

Upgrading means moving up the value chain, so processing the fibre into yarn and garments raises the value retained at home. Continuing to ship unprocessed fibre keeps the economy dependent on low-value primary exports.

Question 50Human Geography (Population, Settlement, Economic Activities)

Which of the following is the best example of a quaternary activity?

  1. Research and development in biotechnology Correct answer.
  2. Coal mining
  3. Retail grocery trade
  4. Steel smelting

Explanation

Quaternary activities involve handling and creating knowledge, such as research, design and decision-making. Smelting is secondary, retail is tertiary and mining is primary.
