Step 1
Step 2
Explain, with the aid of a labelled diagram, how it was formed.
Answer
Cliffs are formed through various erosional processes:
-
Hydraulic Action: Waves crash against the cliff face, causing air to become trapped in cracks and crevices. The pressure from the trapped air can cause pieces of rock to break off.
-
Abrasion: As waves smash into the cliff, they carry sand and rocks which grind against the cliff, further eroding it over time.
A labelled diagram of a cliff formation would typically include:
- A depiction of the cliff face
- Arrows indicating wave action
- Labels for hydraulic action and abrasion processes
The combination of these processes over time can lead to the formation of steep cliffs along coastlines.
