Question
- A. The breaking down of rocks into smaller pieces
- B. The movement of sediment along the coast
- C. The chemical alteration of minerals in rocks
- D. The deposition of sand on beaches
Answer
The correct answer is The breaking down of rocks into smaller pieces.
Explanation
The correct option is The breaking down of rocks into smaller pieces. The breaking down of rocks into smaller pieces is correct because it directly matches the approved learning objective to explain coastal erosion processes including hydraulic power, abrasion and attrition. This belongs to Coastal landscapes in the UK (optional route) within Section C: Physical landscapes in the UK, so the answer must stay focused on the geographical process, evidence, place, or impact named by the curriculum. The other options are weaker because they move away from Coastal landscapes in the UK (optional route), reverse the geographical relationship, or make a broader claim than the objective supports.
Common mistake
Misunderstanding Erosion Processes
Students often confuse hydraulic power with abrasion and attrition, thinking they are the same process.
Clarify that hydraulic power involves the force of water impacting surfaces, while abrasion is the wearing away of rock by sediment carried by water, and attrition is the breaking down of rocks as they collide with each other.
