Question 1
Which process involves the wearing away of rocks by the impact of waves throwing pebbles against a cliff face?
- A) Hydraulic action
- B) Abrasion
- C) Attrition
- D) Solution
Show answer
Answer: Abrasion
Abrasion occurs when waves transport sediment, such as pebbles and sand, and hurl them against the cliff face. This constant grinding action acts like sandpaper, gradually wearing away the rock surface over time.

Question 2
What is the name of the process where rocks carried by the sea bash against each other and become smaller and more rounded?
Show answer
Answer: Attrition
As waves transport load along the coast, the particles collide with one another. These repeated impacts cause the rocks to break into smaller fragments and become smoother and more rounded in shape.

Question 3
Which landform is created when a crack in a headland is widened by hydraulic action and abrasion?
- A) Stack
- B) Wave-cut platform
- C) Cave
- D) Spit
Show answer
Answer: Cave
Erosion focuses on lines of weakness in a headland, such as joints or faults. Hydraulic action and abrasion enlarge these weaknesses to create a hollow space, which eventually develops into a cave.
