O Level Geography: The Natural Environment — Practice Questions

These are original practice questions written in the style of Cambridge O Level Geography (2217) assessment objectives. They are not taken from any past paper and are not endorsed by Cambridge International.

Use these questions alongside the The Natural Environment study guide and revision notes.

Section A

1. State the process that causes both earthquakes and volcanic eruptions to occur at the same general locations. [2]

2. Complete the table by naming the dominant process and a typical landform for each course of a river.

Course	Dominant process	Typical landform
Upper	?	?
Middle	?	?
Lower	?	?

[4]

3. Name two processes of coastal erosion. [2]

4. State the difference between weather and climate. [2]

5. State one adaptation of tropical rainforest vegetation and one adaptation of hot desert vegetation to their respective climates. [2]

Section B

6. A region is hit by a volcanic eruption. Scientists confirm the region sits on a converging plate boundary.

(a) Explain why volcanic activity is common at this type of plate boundary. [2] (b) Suggest two effects this eruption could have on the local population. [2] (c) Suggest two ways the impact of future eruptions in this region could be managed. [2]

7. A river valley shows steep sides and a fast-flowing channel near its source, but wide meanders and a broad floodplain further downstream.

(a) Name the dominant erosion process in the upper course, and the landform it typically produces. [2] (b) Explain why lateral erosion becomes more significant than vertical erosion in the middle course. [2] (c) Name one hard engineering and one soft engineering approach a community downstream could use to manage flood risk. [2]

8. A stretch of coastline shows a headland with caves, an arch, and a stack, alongside a nearby beach.

(a) Explain how differential erosion produces a headland and bay coastline. [2] (b) Explain the sequence by which a cave develops into an arch and then a stack. [2] (c) Explain why the nearby beach is a depositional feature rather than an erosional one. [1]

9. A school weather station keeps a maximum-minimum thermometer inside a Stevenson Screen.

(a) Describe two features of a Stevenson Screen that help the thermometers inside record accurate air temperatures. [2] (b) On one day the maximum thermometer reads 31 °C and the minimum thermometer reads 19 °C. Calculate the temperature range for that day. [1] (c) Name the instrument used to measure wind direction. [1]

10. Compare tropical rainforest and hot desert environments in terms of climate, vegetation adaptation, and one human threat to each. [6]

Answers

1. Both occur mainly at or near plate boundaries, where tectonic plates move apart, towards each other or past one another [1]. Earthquakes occur at all three boundary types (constructive, destructive and conservative); volcanic activity occurs at constructive and destructive boundaries, where magma reaches the surface [1].

2. Upper: vertical erosion; V-shaped valley or waterfall [2]. Middle: lateral erosion; meander [1]. Lower: deposition; floodplain or delta [1].

3. Any two of: hydraulic action, abrasion, attrition, solution [2].

4. Weather is the short-term, day-to-day state of the atmosphere; climate is the long-term average pattern over decades [2].

5. Rainforest: dense, layered canopy competing for light [1]. Desert: water storage and reduced leaf surface area to limit water loss (for example, in cacti) [1].

6. (a) At a converging plate boundary, one plate is forced beneath another (or the plates collide), generating friction and pressure that melts rock into magma, which then rises and can erupt at the surface [2]. (b) Any two of: ground shaking or tremors, ash fall affecting health and agriculture, damage to buildings and infrastructure, loss of life, disruption to transport and communication [2]. (c) Any two of: early-warning monitoring systems, evacuation planning, building codes designed to withstand seismic or ash-related stress, restricting settlement in the highest-risk zones [2].

7. (a) Vertical erosion [1], producing a V-shaped valley (or a waterfall where a band of harder rock is present) [1]. (b) As gradient decreases downstream, the river has less energy for cutting straight down, so its energy is increasingly directed sideways against the banks, causing the channel to widen and swing, which is how meanders develop [2]. (c) Hard engineering: for example, a dam, levee, or channel straightening [1]. Soft engineering: for example, floodplain zoning or upstream afforestation [1].

8. (a) Where a coastline is made of alternating bands of hard and soft rock, the softer rock erodes faster than the harder rock, creating bays where the soft rock has been cut back and headlands where the harder rock remains projecting into the sea [2]. (b) Waves first exploit a weakness in a headland to erode a cave; continued erosion from both sides of a narrow headland can break through the cave to form an arch; when the arch’s roof eventually collapses under further erosion, the seaward section is left standing separately as a stack [2]. (c) The beach is a depositional feature because it is formed from sediment (sand or shingle) that has been transported and then deposited by wave action, rather than from rock being worn away [1].

9. (a) Any two of, 1 mark each: painted white to reflect the sun’s heat; louvred (slatted) sides so that air circulates freely while direct sunlight is kept off the thermometers; raised on legs above the ground so readings are not affected by heat from the ground surface; sited in an open space away from buildings and trees so that readings are representative [2]. (b) 31 − 19 = 12 °C [1]. (c) Wind vane [1].

10. A strong answer should compare across all three dimensions: climate (tropical rainforest, which has an equatorial climate — consistently high temperature and heavy rainfall throughout the year; hot desert — very low rainfall and a wide diurnal temperature range) [2]; vegetation adaptation (rainforest — dense, layered canopy competing for light; desert — water storage and reduced leaf surface area to limit water loss) [2]; and one human threat to each (rainforest — deforestation for timber or agriculture; desert — overgrazing or irrigation-driven land degradation) [2]. Full marks require the comparison to link climate, adaptation and human impact together for each environment, rather than listing facts about each in isolation.

A note on exam technique for this topic

The single most reliable way to lose marks on this theme is naming a landform correctly but never explaining the process that formed it — examiners are consistently looking for the process-to-landform link (why a meander forms, not just that it exists), so practise pairing every named feature with its formative process as a fixed habit. The same applies to flood and coastal management: state explicitly whether a strategy is hard or soft engineering, since the two are often examined as a deliberate contrast rather than an open list. For the climate and vegetation content, always connect the specific climatic stress (excess water and competition for light, or water scarcity and heat) to the adaptation it produces, and then to a human impact, since Paper questions frequently ask you to trace all three links in a single answer.
