Cambridge IGCSE Geography: The Natural Environment (0460)

This guide covers Theme 2 – The Natural Environment, the second of three themes in Cambridge IGCSE Geography (0460), 2025-2026 series. Where Theme 1 looked at people – population and settlement – Theme 2 turns to physical processes: how the Earth’s crust moves, how rivers and coasts shape the land, how weather is recorded, and how climate and vegetation are connected.

Where this fits in 0460

Theme 2 is examined in Paper 1 (Geographical Themes) alongside Themes 1 and 3, and its physical skills – reading climate graphs, interpreting hazard maps, describing landform diagrams – are also drawn on in Paper 2 (Geographical Skills). Several of its five sub-topics require a named case study, so candidates need at least one real, located example ready for each hazard or ecosystem the syllabus lists.

Syllabus coverage

CAMBRIDGE IGCSE GEOGRAPHY (0460) — THEME 2 THE NATURAL ENVIRONMENT

2.1 Earthquakes and volcanoes

• The main types and features of volcanoes (strato/composite cones, shield volcanoes; crater, vent, magma chamber) and of earthquakes (epicentre, focus, magnitude)
• The global distribution of earthquakes and volcanoes, linked to the pattern of tectonic plates, plate movement, subduction zones, and constructive/divergent, destructive/convergent and conservative plate boundaries
• The causes of earthquakes and volcanic eruptions and their effects on people and the environment, including that volcanoes present both hazards and opportunities
• What can be done to reduce the impacts of earthquakes and volcanoes
• A required case study of one earthquake and one volcano

2.2 Rivers

• The main hydrological characteristics of rivers (width, depth, speed of flow, discharge) and drainage basins (watershed, tributary, confluence)
• Processes operating in a drainage basin: interception, infiltration, throughflow, groundwater flow, evaporation and overland flow
• How rivers erode, transport and deposit, and the landforms these processes create – long profile and cross-sectional shape, waterfalls, potholes, meanders, oxbow lakes, deltas, levées and flood plains
• Why rivers present hazards (flooding, erosion) as well as opportunities, and how flood impacts can be managed
• A required case study of the opportunities, hazards and management of a river or rivers

2.3 Coasts

• How the sea and wind erode, transport and deposit, and the resulting landforms – cliffs, wave-cut platforms, caves, arches, stacks, stumps, bay and headland coastlines, beaches, spits and coastal sand dunes
• Coral reefs and mangrove swamps, and the conditions needed for them to develop
• Coastal hazards, including coastal erosion and tropical storms, and how their impacts can be managed
• A required case study of the opportunities, hazards and management of an area or areas of coastline

2.4 Weather

• How weather data are collected, including the Stevenson Screen’s characteristics, siting and use, and instruments such as the rain gauge, maximum-minimum thermometer, wet-and-dry bulb thermometer, sunshine recorder, barometer, anemometer, wind vane and simple digital instruments
• Making calculations from weather-instrument data, and interpreting graphs and diagrams of weather and climate

2.5 Climate and natural vegetation

• The characteristics of two climates – equatorial and hot desert – described through temperature (hottest/coolest month means, annual range) and precipitation (amount and seasonal distribution, including convection and relief rainfall)
• The factors behind these characteristics: latitude, pressure systems, winds, distance from the sea, altitude and ocean currents, alongside climatic graphs showing each climate’s temperature and rainfall pattern
• The characteristics of tropical rainforest and hot desert ecosystems, and the relationship between vegetation, soil, wildlife and climate within each
• The causes and effects of tropical rainforest deforestation, locally and globally, and on people
• A required case study of an area of tropical rainforest and an area of hot desert

Case studies are worth planning early rather than late. A well-chosen example often does double duty: a coastal case study of a delta or low-lying coastline, for instance, can support both the river sub-topic (opportunities and flood hazards of living on a delta) and the coasts sub-topic (coastal erosion management), because 2.2’s guidance explicitly lists deltas among the flood-plain and delta opportunities candidates should be able to discuss. Similarly, a single well-researched hot desert region can supply both the climate sub-topic’s temperature and rainfall data (2.5) and act as the required desert ecosystem case study, so it is worth choosing locations that can be reused across sub-topics rather than memorising five completely unconnected places.

How to approach it

Theme 2’s five sub-topics fall into two exam styles worth preparing differently. Weather (2.4) is largely instrument-and-diagram recall, so drilling instrument names against what they measure pays off quickly. The other four sub-topics are process-and-case-study questions: examiners typically give a labelled diagram or photograph of a landform and ask candidates to name the process that formed it, then follow up by asking for a named, located case study. Keep one concise case study per hazard type – an earthquake, a volcano, a river, a coastline, a rainforest area and a desert area – with two or three specific facts each (location, what happened, what was done about it), since vague or unnamed examples lose marks even when the general process explanation is correct. Where sub-topics overlap (coastal erosion and river erosion both use similar landform vocabulary), be precise about which agent – river, sea or wind – is doing the eroding in a given answer, since examiners mark process explanations against the specific environment named in the question.
