Secondary 2 Geography Quiz - Physical Geography
Answer Key
Section A: Short Answer Questions
1. Name the four spheres of the Earth. [4]
(a) Atmosphere
(b) Hydrosphere
(c) Lithosphere
(d) Biosphere
[Marking note: 1 mark each. Accept minor spelling variations if clearly identifiable.]
2. Define the term lithosphere. [1]
The lithosphere is the solid, rocky outer layer of the Earth, consisting of the crust and the uppermost part of the mantle.
[Marking note: Must refer to the solid/rocky outer layer. Do not accept "land" or "ground" alone.]
3. State two ways in which the hydrosphere is important to human activities. [2]
(a) Provides water for drinking / domestic use / agriculture / industry.
(b) Supports fishing / food source / transportation / hydroelectric power.
[Marking note: 1 mark each. Accept any valid use. Answers must relate to human activities, not just natural processes.]
4. What is the difference between weather and climate? [2]
Weather: The day-to-day / short-term condition of the atmosphere at a particular place and time (e.g., sunny, rainy, windy).
Climate: The average / long-term pattern of weather conditions in a place over a long period of time (usually 30+ years).
[Marking note: 1 mark for each correct distinction. Key idea: weather = short-term; climate = long-term average.]
5. Name the layer of the atmosphere in which we live and where most weather occurs. [1]
Troposphere
[Marking note: Spelling must be close. Accept "tropo-sphere" but not "stratosphere".]
Section B: Data and Diagram Interpretation
6. Identify Layer X (the lowest layer of the atmosphere) shown in Figure 1. [1]
Troposphere
7. At approximately what altitude does the troposphere end according to Figure 1? [1]
Approximately 10 km (accept 9–11 km)
8. State one characteristic of the troposphere. [1]
- It is the layer closest to the Earth's surface.
- It contains most of the atmosphere's water vapour.
- Most weather phenomena occur in this layer.
- Temperature generally decreases with altitude in this layer.
[Marking note: Accept any one valid characteristic.]
9. The ozone layer is found in which layer of the atmosphere? [1]
Stratosphere
10. Explain why the troposphere is important for life on Earth. [2]
The troposphere contains the air (oxygen) that living organisms need to breathe. It also contains water vapour, which is essential for the water cycle and for producing precipitation that provides fresh water. Additionally, most weather occurs in the troposphere, which influences conditions for agriculture and human activities.
[Marking note: 2 marks for a well-explained answer with at least two valid points linked to life. 1 mark for one valid point.]
11. What is the highest average monthly temperature recorded? [1]
29°C
12. In which month does the city receive the highest rainfall? [1]
December
13. Calculate the difference between the highest and lowest monthly rainfall values. Show your working. [2]
Highest rainfall = 280 mm (December)
Lowest rainfall = 70 mm (July)
Difference = 280 − 70 = 210 mm
[Marking note: 1 mark for correct working; 1 mark for correct answer. Award 1 mark if only answer is shown without working.]
14. Describe the relationship between temperature and rainfall shown in Table 1. [2]
When rainfall is high (e.g., December, January), temperatures tend to be slightly lower. When rainfall is low (e.g., June, July), temperatures tend to be higher. There is an inverse / negative relationship between rainfall and temperature in this city.
[Marking note: 1 mark for identifying the pattern; 1 mark for describing the relationship (inverse/negative). Accept answers that note the general trend even if temperatures do not vary dramatically.]
Section C: Structured Response
15. (a) What is the water cycle? [1]
The water cycle is the continuous movement of water through the Earth's spheres (atmosphere, hydrosphere, lithosphere, biosphere) through processes such as evaporation, condensation, precipitation, and runoff.
(b) Name the process by which water changes from a liquid to a gas in the water cycle. [1]
Evaporation
(c) Explain how deforestation can disrupt the water cycle. [2]
Deforestation removes trees, which reduces transpiration (the release of water vapour from leaves into the atmosphere). This decreases the amount of moisture in the air, which can lead to reduced cloud formation and less rainfall in the area. Additionally, without tree roots to absorb water, more water runs off the surface, increasing the risk of flooding and soil erosion, and reducing the amount of water that infiltrates into the ground to replenish groundwater.
[Marking note: 2 marks for a clear explanation with at least two linked points. 1 mark for one valid point with some explanation.]
16. (a) Name the process that causes cracks in the cliff face shown above. [1]
Weathering (accept: physical weathering / freeze-thaw weathering / chemical weathering)
(b) Describe how waves can cause the cliff to retreat over time. [3]
Waves erode the base of the cliff through hydraulic action (force of water hitting the rock) and abrasion (rocks and sediment carried by waves grinding against the cliff face). This creates a notch at the base of the cliff. Over time, the notch deepens and the overhanging rock becomes unsupported. Eventually, the overhang collapses under its own weight. The broken material is then carried away by waves, and the process repeats, causing the cliff to retreat inland over time.
[Marking note: Award marks as follows: 1 mark for identifying erosion by waves; 1 mark for describing the formation of a notch/cave at the base; 1 mark for explaining collapse and repetition leading to retreat. Maximum 3 marks.]
17. Explain two ways in which human activities can affect the biosphere. [4]
(a) Deforestation — Clearing forests for agriculture, urban development, or logging destroys habitats, leading to loss of biodiversity. It also removes plant species that contribute to oxygen production and carbon dioxide absorption, disrupting ecosystems.
(b) Pollution — Releasing chemicals, plastics, and waste into the environment contaminates soil, water, and air. This harms organisms, disrupts food chains, and can lead to species decline or extinction. For example, oil spills in oceans kill marine life and damage coastal ecosystems.
[Marking note: 2 marks per way. Award 1 mark for identifying the human activity and 1 mark for explaining its effect on the biosphere. Accept other valid examples such as overfishing, urbanisation, introduction of invasive species, or agriculture.]
18. (a) Define the term natural hazard. [1]
A natural hazard is a naturally occurring event or phenomenon that has the potential to cause damage to the environment, harm to people, or destruction of property.
(b) Give one example of a natural hazard that affects the lithosphere. [1]
Earthquake / volcanic eruption / landslide / tsunami
[Marking note: Accept any valid example. Tsunami is acceptable as it originates from lithospheric/seismic activity.]
19. Describe how the atmosphere helps to protect life on Earth. In your answer, refer to at least two protective functions. [3]
The atmosphere protects life on Earth in several ways. First, the ozone layer in the stratosphere absorbs harmful ultraviolet (UV) radiation from the Sun, preventing it from reaching the surface and causing damage such as skin cancer and harm to plants. Second, the atmosphere acts as a blanket, trapping heat through the greenhouse effect, which keeps the Earth's temperature warm enough to support life. Third, the atmosphere burns up most meteoroids before they reach the Earth's surface, preventing impacts that could cause destruction.
[Marking note: 1 mark for each valid protective function, up to a maximum of 3. Answers must describe the function, not just name it.]
20. A student claims: "The four spheres of the Earth work independently of one another."
Do you agree with this statement? Explain your answer with reference to at least one example of how two spheres interact. [3]
I disagree with this statement. The four spheres of the Earth are interconnected and constantly interact with one another. For example, the hydrosphere and atmosphere interact through the water cycle: water from oceans and rivers (hydrosphere) evaporates into the atmosphere, forms clouds through condensation, and falls back to the Earth as precipitation, which then flows over the lithosphere and supports life in the biosphere. Another example is how the biosphere interacts with the atmosphere — plants (biosphere) take in carbon dioxide and release oxygen through photosynthesis, which changes the composition of the atmosphere. These interactions show that the spheres do not work independently.
[Marking note: Award 1 mark for stating disagreement (or agreement with a well-justified counter-argument). Award 1 mark for providing a valid example of interaction between two spheres. Award 1 mark for explaining the interaction clearly. Maximum 3 marks.]
