Secondary 1 Geography Quiz - Physical Geography

Answer Key


Total Marks: 40


Section A: The Earth's Structure and Plate Tectonics (Questions 1–5)


1. Name the four main layers of the Earth, starting from the outermost layer. (4)

LayerMark
Crust1
Mantle1
Outer core1
Inner core1

Answer: Crust, Mantle, Outer core, Inner core

Marking note: Award 1 mark for each correct layer in the correct order. If the order is reversed or wrong, deduct 1 mark per error (minimum 0). All four must be named for full marks.


2. State two differences between the Earth's crust and the Earth's mantle. (2)

Answer (any two of the following, 1 mark each):

(a) The crust is the outermost layer, while the mantle lies beneath the crust.
(b) The crust is solid and rigid, while the mantle is partially molten (semi-solid/plastic) in the asthenosphere.
(c) The crust is thinner (5–70 km thick) compared to the mantle (approximately 2,900 km thick).
(d) The crust is composed mainly of lighter rocks (e.g., granite and basalt), while the mantle is composed of denser, ultramafic rocks (e.g., peridotite).
(e) The crust is cooler in temperature compared to the mantle, which is extremely hot.

Marking note: Accept any two valid differences. Do not award marks for vague answers such as "they are different" without specifying how.


3. What is a tectonic plate? (1)

Answer: A tectonic plate is a large, rigid slab of solid rock made up of the Earth's crust and the uppermost part of the mantle (the lithosphere) that moves slowly over the semi-fluid asthenosphere.

Marking note: Award 1 mark for a clear definition that includes the idea of a large rigid section of the lithosphere that moves. Accept simplified answers such as "a large piece of the Earth's crust that moves slowly."


4. (a) State the type of plate boundary shown. (1)

Answer: Convergent plate boundary (destructive boundary).

Marking note: Accept "destructive boundary" or "convergent boundary." Award 1 mark.

(b) Explain why volcanic islands form at this type of plate boundary. (2)

Answer:

  • When an oceanic plate subducts (sinks) beneath another plate, it descends into the mantle where temperatures are very high. (1)
  • The subducting plate melts, and the magma produced rises through the overlying plate to the surface, forming volcanoes/volcanic islands. (1)

Marking note: Award 1 mark for describing subduction and 1 mark for explaining that the melting produces magma that rises to form volcanoes. Answers must link subduction to magma generation for full marks.


5. Label the diagram. (5)

Answer:

LabelFeatureMark
1Oceanic crust1
2Continental crust1
3Subduction zone1
4Magma chamber1
5Volcano1

Marking note: Award 1 mark for each correctly placed label. Labels must point to the correct feature. If a student writes the correct word but points to the wrong feature, award 0 for that label.


Section B: Weathering and Erosion (Questions 6–10)


6. Define the term weathering. (1)

Answer: Weathering is the breaking down or dissolving of rocks and minerals on the Earth's surface by physical, chemical, or biological processes, without the movement of the broken material.

Marking note: Award 1 mark for a definition that includes the idea of rock breakdown in situ (in place). Do not accept answers that describe erosion (which involves movement/transport).


7. Complete the table. (3)

Answer:

DescriptionType of Weathering
(i) Rocks break apart due to repeated heating and cooling.B (Physical/mechanical weathering)
(ii) Water reacts with minerals in rocks and dissolves them.A (Chemical weathering)
(iii) Plant roots grow into cracks in rocks and split them apart.C (Biological weathering)

Marking note: Award 1 mark for each correct match. All three must be correct for 3 marks.


8. (a) Suggest a reason for the difference in mass loss between the two blocks. (1)

Answer: Vinegar is an acid, which reacts chemically with the calcium carbonate in limestone, dissolving it. Plain water does not react chemically with limestone, so Block B experienced little or no chemical weathering.

Marking note: Award 1 mark for identifying that the acid in vinegar caused chemical weathering/dissolution of the limestone.

(b) What type of weathering does this experiment model? (1)

Answer: Chemical weathering.

Marking note: Award 1 mark for "chemical weathering." Accept "carbonation" or "dissolution" as alternative answers.


9. Explain how freeze-thaw weathering breaks down rocks. (3)

Answer (award 1 mark for each valid point, maximum 3):

  1. Water seeps into cracks/joints in the rock. (1)
  2. When the temperature drops below 0°C, the water freezes and expands (by approximately 9%). (1)
  3. The expansion exerts pressure on the cracks, widening them. (1)
  4. Repeated cycles of freezing and thawing cause the cracks to enlarge further until pieces of rock eventually break off. (1)

Marking note: Award up to 3 marks. The answer must include: water entering cracks, freezing/expansion, and the rock breaking apart. For full marks, the answer should convey the repeated nature of the process.


10. Distinguish between weathering and erosion. Give one key difference. (2)

Answer:

WeatheringErosion
DifferenceWeathering is the breakdown of rocks in place (in situ) without movement.Erosion is the wearing away and removal/transport of rock material by agents such as water, wind, ice, or gravity.

Marking note: Award 2 marks for a clear distinction that contrasts "breakdown in place" with "wearing away and removal/transport." Award 1 mark if only one side is correctly described. Do not award marks for vague answers.


Section C: Rivers and River Processes (Questions 11–15)


11. Match each river process to its correct definition. (4)

Answer:

ProcessDefinition
ErosionRocks are worn away by the force of the river
TransportationMaterial is carried along by the river
DepositionMaterial is dropped and settles when the river loses energy
CorrasionWeaker rocks along the river bank are worn away by the river's load

Marking note: Award 1 mark for each correctly matched pair. All four must be correct for 4 marks. If a student draws lines, each correct line = 1 mark.


12. State the three main ways a river transports its load. (3)

Answer (1 mark each):

(a) Suspension – fine particles (e.g., silt, clay) are carried within the water.
(b) Saltation – larger particles (e.g., sand, small pebbles) bounce or hop along the river bed.
(c) Traction – the largest, heaviest rocks and boulders are rolled or dragged along the river bed.

Marking note: Award 1 mark for each correct transport process. Accept "solution" (dissolved minerals carried in the water) as an alternative to any one of the above for 1 mark. Do not award more than 3 marks total.


13. Describe two features of a river valley in its upper course. (2)

Answer (any two of the following, 1 mark each):

(a) The valley has a V-shaped cross-section with steep sides.
(b) The river channel is narrow and shallow.
(c) There are large boulders/rocks on the river bed.
(d) The river flows swiftly/rapidly due to the steep gradient.
(e) There may be waterfalls or rapids where the river flows over rocks of different hardness.

Marking note: Award 1 mark for each correct feature described. Answers must describe features visible in or consistent with an upper-course river valley.


14. Explain why a river deposits its load when it reaches a flat, low-lying area such as a floodplain. (2)

Answer:

  • When a river reaches a flat area, the gradient decreases, so the river's speed/velocity decreases. (1)
  • The river therefore loses energy and can no longer transport its load, so it drops/deposits the material. (1)

Marking note: Award 1 mark for identifying reduced speed/velocity and 1 mark for linking this to loss of energy and deposition. Both marks are required for full marks.


15. (a) On which side of the meander does erosion mainly occur? (1)

Answer: The outer bank (the outside of the bend).

Marking note: Award 1 mark. Accept "outside of the meander bend."

(b) Give a reason for your answer in (a). (1)

Answer: The water flows fastest on the outer bank of the meander because of the centrifugal force/effect, giving the river more energy to erode the bank.

Marking note: Award 1 mark for explaining that water velocity is higher on the outer bank, leading to greater erosion. Accept references to centrifugal force or the water being "thrown" to the outside of the bend.


Section D: Coasts and Coastal Processes (Questions 16–20)


16. What is a wave? (1)

Answer: A wave is a ridge of water that moves across the surface of the sea/ocean, caused by wind blowing across the water's surface. It transfers energy through the water.

Marking note: Award 1 mark for a definition that includes the idea of wind creating a movement of water/energy across the sea surface.


17. Name landform X (the isolated rock column standing in the sea away from the cliff). (1)

Answer: Sea stack.

Marking note: Award 1 mark. Accept "stack."


18. Describe the process of hydraulic action and explain how it contributes to coastal erosion. (3)

Answer (award 1 mark for each valid point, maximum 3):

  1. Hydraulic action occurs when waves crash against a cliff face with great force. (1)
  2. The force of the water compresses air trapped in cracks and joints in the rock. (1)
  3. When the wave retreats, the compressed air expands rapidly, exerting pressure on the cracks. (1)
  4. Repeated compression and expansion weakens the rock, causing pieces to break away from the cliff. (1)

Marking note: Award up to 3 marks. For full marks, the answer must describe both the compression of air in cracks and the weakening/breaking of the rock. Answers that only describe waves hitting the cliff without mentioning air compression receive a maximum of 1 mark.


19. (a) Which beach is more likely to be a destructive wave beach? (1)

Answer: Beach B.

Marking note: Award 1 mark.

(b) Give one reason for your answer. (1)

Answer: Destructive waves have powerful/high-energy waves that erode the coastline and transport material offshore, leaving behind larger pebbles and coarse sediment. Beach B has large pebbles and powerful waves, which are characteristics of a destructive wave beach.

Marking note: Award 1 mark for linking powerful waves and/or large pebbles to destructive waves. Accept answers that state destructive waves have high energy and erode the beach.


20. Explain how a sea stack is formed. (4)

Answer (award 1 mark for each valid step in the sequence, maximum 4):

  1. Waves erode lines of weakness (cracks/joints) in a headland through hydraulic action and abrasion, forming caves on both sides. (1)
  2. Continued erosion causes the two caves to erode further and eventually join to form a natural arch. (1)
  3. The top of the arch is weakened by weathering (e.g., freeze-thaw, biological weathering) and further wave erosion, and eventually collapses. (1)
  4. This leaves an isolated pillar of rock standing separately from the cliff, called a sea stack. (1)

Marking note: Award 1 mark for each correct stage in the sequence: headland → caves → arch → collapse → stack. The answer must show a logical sequence. If the sequence is incomplete or out of order, award marks only for correct individual points (maximum 4).
