Cameroon GCE O-Level Geology study plan

Define the scope of geology as an O-Level subject and list the main branches it covers (physical, historical, economic, environmental).

Explain the internal structure of the Earth (crust, mantle, outer core, inner core) and state the evidence used to infer each layer.

Distinguish between the three main rock types and give at least two Cameroonian or West African examples of each.

Describe the rock cycle and trace how one named rock type can be transformed into the other two.

Practise drawing and labelling a simple cross-section of the Earth from memory.

Identify the physical properties used to identify minerals (hardness, cleavage, lustre, streak, colour, specific gravity) and apply them to 10 common minerals.

Use Mohs' hardness scale to rank minerals and explain why hardness is more reliable than colour for identification.

Describe the formation of igneous rocks and distinguish intrusive from extrusive textures with named examples.

Explain how sedimentary rocks form and classify them into clastic, chemical and organic types.

Explain how metamorphic rocks form and distinguish foliated from non-foliated textures.

State the theory of plate tectonics and describe the three types of plate boundary with the landforms associated with each.

Relate earthquakes and volcanoes to plate margins and explain why Cameroon's volcanic line is active.

Label the parts of a volcano and a fold/fault diagram and explain how each forms.

Describe the effects of earthquakes and volcanic eruptions on people and the environment, and outline basic mitigation measures.

Interpret a simple geological map or block diagram to identify strike, dip and rock relationships.

Describe the processes of weathering, erosion, transportation and deposition, and distinguish physical from chemical weathering.

Explain the development of soils and identify the main soil types found in Cameroon.

Describe the work of rivers, wind and groundwater in shaping landforms and give named examples.

Outline the rock record: superposition, cross-cutting relationships and index fossils, and use them to order events.

Complete a timed 20-question mixed quiz on rocks, minerals, tectonics and surface processes.

Define a fossil and describe the conditions needed for fossilisation, with examples of fossil types.

Explain how the geological time scale is divided and place the main eras and periods in order.

Relate major events in Earth history (origin of life, mass extinctions, appearance of humans) to the time scale.

Describe the geological history and stratigraphy of Cameroon in outline, including the Chad Basin and coastal sedimentary basins.

Interpret a simple stratigraphic column to determine relative ages.

List Cameroon's main mineral and energy resources and state where each is found.

Explain the difference between reserves and resources and describe how an ore deposit forms.

Outline the methods of mineral exploration and the environmental impacts of mining and quarrying.

Describe renewable and non-renewable energy sources and evaluate their relevance to Cameroon.

Discuss the environmental consequences of resource extraction and propose mitigation measures.

Explain the causes and effects of landslides, soil erosion, flooding and desertification in Cameroon.

Describe groundwater occurrence, aquifers and the causes of water pollution.

Outline waste management, deforestation and climate-change issues from a geological perspective.

Practise structured essay answers on environmental geology under timed conditions.

Evaluate the strengths and weaknesses of your own answers against a marking checklist.

Revise all topics using a condensed summary sheet of key definitions, diagrams and processes.

Complete two full timed mock papers under exam conditions.

Identify and re-teach the three weakest topics revealed by the mocks.

Practise interpreting unfamiliar diagrams, maps and data-based questions.

Finalise a one-page formula/diagram sheet for last-minute revision.
