Question 1Geography
Which type of plate boundary is associated with the formation of a deep ocean trench and a chain of volcanic island arcs?
- A divergent boundary where two oceanic plates move apart at a mid-ocean ridge
- A transform boundary where two plates slide horizontally past each other
- A convergent boundary where an oceanic plate subducts beneath another oceanic plate Correct answer.
- A convergent boundary where two continental plates collide and crumple
Explanation
When two oceanic plates converge, the denser plate subducts, creating a deep trench, and the rising magma forms a volcanic island arc. Continental collision instead produces fold mountains without a trench, and conservative or divergent margins do not generate subduction-related arcs.
Question 2Geography
A river flows from a mountainous source to the sea. Which sequence correctly describes the typical downstream changes in its channel and load?
- Gradient increases, discharge decreases, and load becomes coarser and more angular
- Gradient increases, discharge increases, and load becomes finer and more rounded
- Gradient decreases, discharge decreases, and load becomes coarser and more angular
- Gradient decreases, discharge increases, and load becomes finer and more rounded Correct answer.
Explanation
Downstream, the river gradient flattens while tributaries raise discharge, and attrition and abrasion reduce load size and round the particles. The opposite combinations misstate either the gradient, the discharge trend, or the way load is modified along the course.
Question 3Geography
Which climatic factor most directly explains why coastal locations usually have a smaller annual temperature range than inland locations at the same latitude?
- Coastal areas experience weaker Coriolis deflection
- The high specific heat capacity of water moderates coastal temperatures Correct answer.
- Inland areas are closer to the jet stream
- Coastal areas receive more direct sunlight than inland areas
Explanation
Water heats and cools more slowly than land because of its high specific heat capacity, so maritime air masses moderate coastal temperatures in both summer and winter. This reduces the annual range compared with continental interiors, which heat and cool rapidly.
Question 4Geography
Which statement best describes the process of chemical weathering by carbonation in a limestone region?
- Rainwater containing dissolved carbon dioxide reacts with calcium carbonate and dissolves it Correct answer.
- Frost expands water in cracks and shatters the rock into angular fragments
- Wind-driven sand abrades the rock surface and smooths it
- Plant roots force joints apart and physically prise blocks of rock loose
Explanation
Carbon dioxide dissolves in rainwater to form weak carbonic acid, which reacts with calcium carbonate in limestone and removes it in solution. This chemical process creates features such as swallow holes and caverns in karst landscapes.
Question 5Geography
Which of the following is the main reason why tropical rainforests have high biodiversity compared with temperate forests?
- Tropical forests have fewer herbivores, so more plant species survive
- Tropical soils are richer in nutrients and support more plant species
- Warm, wet conditions allow continuous growth and many specialised ecological niches Correct answer.
- Tropical forests experience greater seasonal temperature variation
Explanation
Constant high temperatures and rainfall allow year-round growth, and the layered structure of the forest creates many microhabitats and specialised niches. This supports a large number of species, even though tropical soils are often nutrient-poor.
Question 6Geography
What is the primary cause of the enhanced greenhouse effect associated with human activity?
- Increased atmospheric concentrations of carbon dioxide and methane from burning fossil fuels and agriculture Correct answer.
- Depletion of the ozone layer by chlorofluorocarbons
- Reduction in solar radiation reaching the Earth's surface
- Increased emission of sulphur dioxide from volcanic eruptions
Explanation
Burning fossil fuels releases carbon dioxide, and livestock and rice cultivation release methane; both trap outgoing long-wave radiation and warm the atmosphere. Ozone depletion and volcanic sulphur dioxide affect different atmospheric processes and are not the main driver of the enhanced greenhouse effect.
Question 7Geography
A settlement located at the point where a river can be crossed easily and where routes converge is best described as having developed for which reason?
- A bridging point and route focus Correct answer.
- A defensive hilltop site
- A wet-point site on a river floodplain
- A gap-town location through a mountain ridge
Explanation
Settlements often grow where a river is shallow or narrow enough to bridge and where several routes meet, making the crossing a natural focus for trade and movement. This is the classic bridging-point and route-focus site factor.
Question 8Geography
Which type of farming is characterised by growing crops and rearing animals mainly to feed the farmer's own family?
- Market gardening
- Plantation agriculture
- Commercial farming
- Subsistence farming Correct answer.
Explanation
Subsistence farming produces food primarily for the farmer and household rather than for sale, often on small plots with little surplus. Commercial, plantation, and market-gardening systems are all oriented towards selling produce.
Question 9Geography
A country's population pyramid has a broad base and narrow apex. Which interpretation is most consistent with this shape?
- A recent baby boom following a period of low fertility
- A large elderly dependent population supported by a small working-age group
- Low birth rates and high life expectancy, typical of a late stage of demographic transition
- High birth rates and low life expectancy, typical of an early stage of demographic transition Correct answer.
Explanation
A broad base shows a large number of young children, indicating high birth rates, while a narrow apex shows few elderly people, indicating lower life expectancy. Together these features characterise an early stage of the demographic transition model.
Question 10Geography
A city experiences rapid in-migration from rural areas. Which consequence is most likely to result directly from this process?
- A decline in the total urban population
- A reduction in demand for urban transport
- Growth of informal settlements on the urban periphery Correct answer.
- A fall in the birth rate of the rural source region
Explanation
Rapid rural-to-urban migration often outpaces the supply of formal housing and services, so newcomers build informal settlements on the outskirts. The other options describe outcomes that do not follow directly from in-migration.
Question 11Geography
An anticyclone (high-pressure system) in the Northern Hemisphere brings settled weather. Which set of conditions best describes this system?
- Converging surface winds with rapidly falling pressure
- Descending air, clear skies, light winds and cold nights in winter Correct answer.
- Strong winds and unsettled weather with passing fronts
- Ascending air, heavy cloud and frequent rain
Explanation
In a high-pressure system air subsides, preventing cloud formation and producing clear skies and light winds. In winter, clear skies allow rapid heat loss at night, producing cold temperatures and frost.
Question 12Geography
Why does the leeward side of a mountain range often receive less rainfall than the windward side?
- The leeward side is at a lower altitude and therefore cooler
- The leeward side faces the prevailing wind and receives more cloud
- Air has already lost much of its moisture on the windward slope and warms as it descends Correct answer.
- Air on the leeward side is always colder and holds more moisture
Explanation
Air rises on the windward slope, cools, and releases moisture as orographic rainfall. As it descends the leeward slope it warms and its relative humidity falls, creating a drier rain-shadow effect.
Question 13Geography
A soil profile in a humid tropical region typically shows a thin humus layer over a deeply weathered, leached horizon. Which process best explains the deep leaching?
- Capillary action draws salts upwards to the surface
- Freezing and thawing breaks down the parent rock into fine particles
- Heavy rainfall washes soluble bases and nutrients downwards through the profile Correct answer.
- Wind erosion removes the topsoil and exposes the subsoil
Explanation
High rainfall in humid tropical areas drives strong downward percolation, removing soluble bases and leaving iron and aluminium oxides behind. This intensive leaching produces deep, nutrient-poor soils such as latosols.
Question 14Geography
What is the main function of a meander in the middle and lower course of a river?
- To create a steep waterfall where the gradient suddenly increases
- To transport water in a straight line with equal erosion on both banks
- To store floodwater permanently behind a natural dam
- To carry water and sediment along a winding path with erosion on the outer bank and deposition on the inner bank Correct answer.
Explanation
In a meander, faster flow on the outer bank causes erosion and forms a river cliff, while slower flow on the inner bank deposits sediment to form a slip-off slope. The channel therefore migrates sideways over time.
Question 15Geography
A coastal area has a strong prevailing wind blowing onshore. Which feature is most likely to develop over time?
- A deep fjord formed by glacial erosion
- A spit extending in the direction of the longshore drift Correct answer.
- A steep cliff formed by chemical weathering
- A raised beach above the present shoreline
Explanation
Onshore winds drive longshore drift, which transports sediment along the coast until the coastline changes direction, allowing a spit to build out. Fjords, raised beaches, and most cliffs relate to other processes such as glaciation or erosion.
Question 16Geography
Which factor most strongly influences the rate at which a population grows in a country with high fertility and falling mortality?
- A rising proportion of elderly dependants
- Improved access to contraception
- Emigration of young adults to other countries
- A large proportion of young people entering their reproductive years Correct answer.
Explanation
When mortality falls while fertility remains high, the population has a large cohort of young people who will soon have children, so natural increase continues even if fertility begins to decline. This population momentum drives rapid growth.
Question 17Geography
Which of the following best explains why the ITCZ (Intertropical Convergence Zone) shifts north and south during the year?
- It moves according to the phases of the moon
- It is fixed over the equator throughout the year
- It is pushed by ocean currents flowing north and south
- It follows the zone of maximum solar heating as the overhead sun migrates between the tropics Correct answer.
Explanation
The ITCZ marks the zone where the trade winds converge, and it migrates with the band of greatest solar heating as the overhead sun moves between the Tropics of Cancer and Capricorn. This shift drives seasonal rainfall patterns in the tropics.
Question 18Geography
A country with a rapidly growing economy shifts from exporting raw materials to manufacturing goods. Which term best describes this change?
- Deindustrialisation
- Industrialisation Correct answer.
- Primary production
- Subsistence agriculture
Explanation
Industrialisation is the growth of manufacturing as a share of the economy, often accompanied by a shift away from reliance on raw-material exports. Deindustrialisation is the opposite trend, while the other options describe primary or subsistence activities.
Question 19Geography
A steep hillside is cleared of vegetation for farming. Which combination of processes is most likely to follow?
- Reduced infiltration, decreased river discharge and stabilised slopes
- Decreased runoff, deeper root binding and slope stability
- Increased surface runoff, soil erosion and risk of landslides Correct answer.
- Increased infiltration, reduced erosion and greater soil fertility
Explanation
Removing vegetation reduces interception and root binding, so more water runs over the surface and soil is easily washed away. On steep slopes this raises the risk of erosion and landslides.
Question 20Geography
Which statement best explains why an area of high atmospheric pressure is associated with descending air?
- Cooling air aloft becomes denser and sinks, raising surface pressure Correct answer.
- Frontal uplift pushes air to high altitude
- Air converges at the surface and is forced upwards
- Warm surface air rises and lowers surface pressure
Explanation
In a high-pressure system, air aloft cools, becomes denser, and subsides towards the surface, increasing the weight of the air column and therefore the surface pressure. Rising and converging air is characteristic of low-pressure systems instead.
Question 21Geography
Two places lie on the same latitude but one is on a western coast and the other on an eastern coast of a continent in the mid-latitudes. Which factor best explains the difference in their annual temperature ranges?
- The direction of prevailing winds and the presence of warm or cold ocean currents offshore Correct answer.
- The altitude of each place above sea level
- The distance of each place from the equator
- The number of daylight hours each receives
Explanation
In the mid-latitudes, prevailing westerlies bring maritime air from the adjacent ocean, and offshore currents determine whether that air is warmed or cooled. A warm current on one coast and a cold current on the other therefore produce contrasting temperature ranges at the same latitude.
Question 22Geography
A river's discharge hydrograph shows a short lag time between peak rainfall and peak discharge, with a high peak. Which drainage basin characteristics best explain this response?
- Permeable rock, gentle slopes and dense forest cover
- Large lake storage within the basin
- Extensive floodplain storage upstream
- Impermeable rock, steep slopes and little vegetation cover Correct answer.
Explanation
Impermeable rock limits infiltration, steep slopes speed water downslope, and sparse vegetation reduces interception, so rainwater reaches the channel quickly. This produces a short lag time and a high flood peak.
Question 23Geography
In a rapidly urbanising low-income city, which strategy would most effectively reduce the health risks associated with inadequate sanitation in informal settlements?
- Increasing private car ownership to improve mobility
- Providing communal water points and improved sewerage or latrine systems with secure tenure Correct answer.
- Relocating all residents to distant rural areas
- Building higher-rise commercial offices in the city centre
Explanation
Access to clean water and safe excreta disposal directly reduces waterborne and sanitation-related disease, and secure tenure encourages residents to invest in improving their homes. The other options do not address the sanitation problem.
Question 24Geography
Which explanation best accounts for the formation of a waterfall where a river crosses a band of resistant rock?
- Differential erosion removes the softer rock downstream, creating a step over which the river plunges Correct answer.
- Longshore drift deposits material across the valley
- The river's gradient decreases suddenly and flow becomes laminar
- Deposition of sediment builds a ridge across the channel
Explanation
The resistant band is eroded more slowly than the softer rock beneath or downstream, so a step develops and the river plunges over it. Undercutting and collapse cause the waterfall to retreat upstream over time.
Question 25Geography
A government wants to reduce the flood risk in a river basin where urban development has increased impermeable surfaces. Which combination of measures is most consistent with integrated catchment management?
- Straightening the channel and removing all floodplain vegetation
- Upstream afforestation, sustainable drainage systems and floodplain zoning Correct answer.
- Building higher embankments only at the river mouth
- Increasing paved area and reducing infiltration
Explanation
Integrated catchment management combines measures across the whole basin: planting trees upstream increases interception, sustainable drainage reduces rapid runoff from urban areas, and zoning keeps vulnerable development off floodplains. Together these lower and slow the flood peak.
Question 26Geography
A rock sample contains minerals arranged in distinct parallel bands that have been folded under intense heat and pressure. Which rock type does this sample most likely represent?
- An intrusive igneous rock
- A clastic sedimentary rock
- A foliated metamorphic rock Correct answer.
- A chemically precipitated sedimentary rock
Explanation
Foliation, the alignment of minerals into parallel bands, develops when rocks are subjected to directed pressure during metamorphism. Igneous rocks crystallise from magma and sedimentary rocks form by deposition, so neither develops this banded, deformed texture.
Question 27Geography
Which process transfers latent heat from the Earth's surface into the atmosphere and is central to the formation of cumulonimbus clouds?
- Evaporation of water followed by condensation at height Correct answer.
- Conduction of heat through the soil
- Advection of cold air along the ground
- Reflection of short-wave radiation by cloud tops
Explanation
Evaporation absorbs latent heat at the surface, and when the rising water vapour condenses aloft it releases that latent heat, warming the air and driving further uplift. This release of energy is what powers the towering convection that builds cumulonimbus clouds.
Question 28Geography
Which term describes the movement of people from one country to another with the intention of settling permanently?
- Circulation
- International migration Correct answer.
- Commuting
- Seasonal migration
Explanation
International migration is the permanent or long-term movement of people across national borders. Commuting and circulation are temporary, repetitive movements within or near a home area, and seasonal migration involves only part of the year.
Question 29Geography
A country has a birth rate of 42 per 1000, a death rate of 12 per 1000, and net migration close to zero. What is its approximate annual rate of natural increase?
- 3.0% Correct answer.
- 30%
- 0.3%
- 5.4%
Explanation
Natural increase equals the birth rate minus the death rate, giving 42 minus 12, or 30 per 1000. Dividing by 10 converts this to a percentage, so the rate is about 3.0% per year.
Question 30Geography
Which feature forms where a river flows from a steep upland valley onto a flat plain and deposits its coarse load?
- An oxbow lake
- A delta
- An alluvial fan Correct answer.
- A plunge pool
Explanation
When a river leaves a steep valley and enters flatter ground, its gradient and velocity fall sharply, so coarse sediment is deposited in a fan-shaped spread. Deltas form where rivers enter standing water such as a lake or sea, not at the foot of a valley.
Question 31Geography
Which characteristic is typical of a commercial extensive cattle-rearing system?
- Large land area with low output per hectare but high output per worker Correct answer.
- Small land area with high labour input per hectare
- Crops grown mainly for household consumption
- Intensive use of greenhouses to control temperature
Explanation
Extensive farming spreads few inputs over large areas, so yields per hectare are low while each worker manages many animals, giving high output per worker. Intensive systems instead concentrate labour and capital on small areas.
Question 32Geography
Which factor most directly determines the porosity of a soil?
- The colour of the surface horizon
- The depth of the parent bedrock
- The rate at which water passes through the soil
- The proportion of pore space between soil particles Correct answer.
Explanation
Porosity is the proportion of a soil's volume made up of voids, so it depends on the arrangement and size range of particles. Permeability, by contrast, describes how quickly water moves through those pores and is a separate property.
Question 33Geography
A government introduces a congestion charge for vehicles entering a city centre. Which outcome is the most direct intended effect of this policy?
- A reduction in traffic volume and related air pollution in the zone Correct answer.
- An increase in the number of private cars entering the zone
- An increase in the birth rate of the urban population
- A rise in rural-to-urban migration
Explanation
A congestion charge raises the cost of driving into a specified area, discouraging unnecessary car journeys and thereby cutting traffic and exhaust emissions. The policy targets transport demand rather than demographic trends.
Question 34Geography
Why does a river's velocity typically increase along its middle course even though its gradient is gentler than in the upper course?
- The river flows over more resistant rock
- Rainfall is heavier in the middle course
- Friction with the bed and banks decreases because the channel is wider and smoother Correct answer.
- The river carries less load than in the upper course
Explanation
In the middle course the channel is wider and deeper with a smoother bed, so a smaller proportion of the water is in contact with rough surfaces. Reduced friction allows velocity to rise despite the gentler slope.
Question 35Geography
A coastal cliff is composed of loosely cemented sandstone at the base and hard limestone above. Which sequence of development is most likely?
- The whole cliff retreats evenly with no change in profile
- Deposition of beach material builds the cliff seawards
- Wave-cut notches form in the sandstone, undercutting the limestone until it collapses Correct answer.
- The limestone erodes first, leaving a projecting sandstone base
Explanation
The weaker sandstone erodes more rapidly under wave attack, so a notch is cut at the base and the overhanging hard limestone becomes unsupported. Collapse of the overhang produces a steep, irregular cliff profile, an example of differential erosion.
Question 36Geography
What is the main reason that tropical rainforests have high biomass despite soils that are often nutrient-poor?
- The soil contains large reserves of weatherable minerals that are never leached
- Low temperatures slow the loss of nutrients from the soil
- Nutrients are stored mainly in the living vegetation and are recycled rapidly through decomposition Correct answer.
- Fertiliser is applied across most of the forest area
Explanation
In the humid tropics, heavy rainfall leaches soluble nutrients from the soil, but high temperatures speed decomposition so that nutrients are quickly taken up by plants and held in the biomass. The nutrient capital therefore resides largely in the vegetation and litter rather than in the soil.
Question 37Geography
Which condition is necessary for a tropical cyclone to develop?
- Location within 5 degrees of the equator where Coriolis force is strongest
- Descending air at the centre of the developing system
- A strong vertical wind shear that tilts the developing storm
- Sea-surface temperatures of at least about 27 degrees Celsius providing abundant latent heat Correct answer.
Explanation
Tropical cyclones require warm ocean water of roughly 27 degrees Celsius or more to supply the latent heat that fuels convection. They also need sufficient Coriolis force to generate rotation, which is why they rarely form within about 5 degrees of the equator.
Question 38Geography
A population pyramid shows a narrow base, a wide middle section, and a small top. Which interpretation is most consistent with this shape?
- A population recovering from a recent famine affecting all ages
- A youthful population with high fertility and rapid growth
- A population with very high death rates among the elderly
- A population with declining births and an ageing workforce Correct answer.
Explanation
A narrow base indicates falling numbers of births, while the broad middle shows a large working-age cohort and the small top a modest elderly group. This shape is typical of a country in the later stages of demographic transition, where fertility has declined and the population is ageing.
Question 39Geography
Which explanation best accounts for the formation of a hanging valley at the junction of a tributary and a glaciated main valley?
- The main glacier eroded its floor more deeply than the smaller tributary glacier Correct answer.
- The main valley was widened by lateral erosion while the tributary was deepened
- Post-glacial rivers cut the tributary back faster than the main valley
- The tributary glacier deposited a terminal moraine across the main valley
Explanation
A large glacier in the main valley abrades and plucks its floor far more deeply than the smaller tributary glacier can. When the ice retreats, the tributary is left perched above the main valley floor, often with a waterfall at the junction.
Question 40Geography
A company locates a steel plant close to an iron-ore field and a coalfield. Which locational factor is best illustrated by this choice?
- Government subsidy for exports
- Access to a skilled labour force
- Availability of a large consumer market
- Proximity to raw materials and energy sources Correct answer.
Explanation
Locating near both ore and coal minimises the cost of transporting bulky, weight-losing raw materials, a classic example of material-oriented industrial location. Labour, subsidies, and markets may also matter but are not what the proximity to ore and coal demonstrates.
Question 41Geography
Which measure would most effectively reduce the urban heat island effect in a densely built city?
- Replacing dark roofs with light-coloured surfaces and increasing street trees Correct answer.
- Building taller concrete towers to increase shading
- Reducing the number of parks to free land for housing
- Paving open ground with asphalt to improve drainage
Explanation
Light-coloured surfaces reflect more solar radiation, and trees provide shade and cool the air through transpiration, both lowering surface and air temperatures. Together these measures reduce the heat stored and released by dense urban fabric.
Question 42Geography
A river basin is underlain by permeable chalk. Which change to a storm hydrograph would most likely result from this geology compared with an impermeable clay basin of similar size?
- A higher peak discharge with no change in baseflow
- A longer lag time and a lower peak discharge Correct answer.
- No change in lag time but a higher baseflow
- A shorter lag time and a higher peak discharge
Explanation
Permeable rock allows water to infiltrate and move slowly underground, delaying its arrival in the channel and spreading the flood peak over a longer period. This produces a longer lag time, a lower peak, and generally higher baseflow.
Question 43Geography
Which process is primarily responsible for the seaward growth of a spit across a river mouth?
- Longshore drift carrying sediment along the coast until the current weakens Correct answer.
- Subsidence of the coastal plain
- Erosion of the headland by hydraulic action
- Upwelling of cold water offshore
Explanation
Longshore drift transports sediment along the shore in the direction of the dominant waves. Where a river mouth interrupts the flow and reduces wave energy, sediment is deposited and builds a ridge that projects across the estuary.
Question 44Geography
Which statement best explains why the dry season in a savanna region is associated with the migration of large herbivores?
- Soils become more fertile, encouraging animals to remain
- Temperatures fall below freezing, so animals seek warmer areas
- Predators become more numerous during the dry season
- Surface water and green grazing become scarce, forcing animals to move towards remaining water sources Correct answer.
Explanation
During the dry season, rainfall ceases, seasonal waterholes shrink, and grasses wither, so herbivores must travel to find food and water. Their movement follows the availability of these resources and reverses when the rains return.
Question 45Geography
A steep, unvegetated slope of weathered regolith receives intense rainfall. Which mass movement is most likely to occur?
- Chemical weathering of bedrock by solution
- A slow creep of soil downhill over many years
- Deposition of a terminal moraine
- A rapid mudflow or debris slide Correct answer.
Explanation
When weathered material on a steep slope becomes saturated, its weight increases and friction between particles falls, so it can move rapidly downslope as a mudflow or debris slide. Creep is far slower, and moraines and chemical weathering are unrelated processes.
Question 46Geography
A country's economy shifts from producing raw materials to manufacturing, and later to services and finance. Which sequence of employment structure best describes this change?
- Secondary, then tertiary, then primary
- Tertiary, then primary, then secondary
- Primary, then secondary, then tertiary Correct answer.
- Primary, then tertiary, then secondary
Explanation
Economic development commonly begins with a dominant primary sector of farming and mining, moves to manufacturing in the secondary sector, and finally to services and finance in the tertiary sector. This progression reflects rising productivity and income.
Question 47Geography
Two towns lie at the same distance from a large city, but one is connected by a motorway and the other only by narrow rural roads. Which explanation best accounts for their different rates of growth?
- The motorway town has greater accessibility, reducing travel time and attracting commuters and firms Correct answer.
- The rural-road town benefits from lower land values and therefore grows faster
- Distance alone determines growth, so both should grow equally
- The motorway town has lower accessibility to markets and employment
Explanation
Improved transport links reduce journey times and costs, raising accessibility to jobs, customers, and suppliers. This attracts residents and businesses, so the well-connected town grows faster than one served only by poor roads.
Question 48Geography
A high-pressure system stalls over a heavily industrialised basin surrounded by mountains. Which outcome is most likely?
- A temperature inversion traps pollutants near the surface Correct answer.
- Strong winds disperse pollutants rapidly
- Rapid uplift carries pollutants into the upper atmosphere
- Heavy rainfall washes pollutants out of the air
Explanation
Descending air in a high-pressure system creates stable conditions, and at night the ground cools quickly, producing a temperature inversion in which warmer air lies above colder surface air. The stable layer prevents vertical mixing, so pollutants accumulate in the basin.
Question 49Geography
A developing country wishes to raise farm incomes without increasing the area cultivated. Which strategy is most consistent with sustainable agricultural intensification?
- Expanding cultivation onto steep, marginal hillsides
- Abandoning irrigation to rely entirely on rainfall
- Increasing yields per hectare through improved seed, irrigation, and soil conservation Correct answer.
- Converting cropland to extensive grazing
Explanation
Sustainable intensification raises output per unit area by combining better seed, reliable water, and conservation of soil fertility, without bringing fragile new land into production. This protects livelihoods while limiting environmental damage.
Question 50Geography
Which combination of factors best explains why tropical rainforests are being cleared for large-scale cattle ranching rather than for smallholder farming?
- High global demand for beef, cheap land, and access provided by new roads Correct answer.
- Low global demand for beef and rising costs of transport
- Rapid decline in the urban population of the region
- Government bans on agricultural expansion and strict forest protection
Explanation
Large-scale ranching expands where international demand for beef is strong, land is inexpensive, and new roads open previously remote forest to investment. These commercial pressures favour extensive pasture over subsistence plots.
