3. Attrition.
4. Solution
5. Compressed air.

Question 3

What is hydraulic action

Answer 3

When the force of the waves erodes the coast as they crash against it

Question 4

What is Abrasion

Answer 4

When eroded material ( load ) in waves crashes against the coastline

Question 5

What is Attrition

Answer 5

when the seas load hits and collides against itself due to ocean currents

Question 6

Whats Solution

Answer 6

When some of the seas load is dissolved by tye water

Question 7

Whats compressed air

Answer 7

Question 8

4. Sea arch
5. Sea cliff
6. Blowhole
7. Wave cut platform
8. Sea cave
9. Sea stack
10. Stump

Question 10

Features of deposition

Answer 10

• The process of deposition works with the processes of erosion
and transportation to create many features.
• As the coast erodes, rock is transported and deposited elsewhere
along the coastline.
• This deposited material can build up over time to form new
features.
