How does the sea erode and shape the land?

Question 1

Erosion

Answer 1

Hydraulic action, Abrasion, Attrition, Solution

Question 2

Transportation

Answer 2

Suspension, Solution, Traction, Saltation

Question 3

Define Hydraulic action

Answer 3

Water is forced into cracks in the rock, is compressed and forces the rock apart

Question 4

Define Abrasion

Answer 4

Loose rocks are thrown against the cliff, wearing away at the rock like sandpaper

Question 5

Define Attrition

Answer 5

Loose rocks are swirled around and are worn in smaller, rounder pieces

Question 6

Define Solution (Erosion)

Answer 6

Seawater dissolves material from the rock

Question 7

Define Suspension

Answer 7

Fine sediment is carried along in suspension in the water

Question 8

Define Solution (Transportation)

Answer 8

Dissolved materials is carried along in solution- you can’t see it

Question 9

Define Traction

Answer 9

Large pebbles and cobbles are rolled along the seabed

Question 10

Define Saltation

Answer 10

Small pebbles are moved when a pebble hits another, causing it to bounce
