Sea And River Erosion

Question 1

Hydraulic action

Answer 1

The power of the water

Question 2

Abrasion

Answer 2

Rocks hitting the cliff and breaking apart and eroding the bottom of a cliff

Question 3

Attrition

Answer 3

Rocks bashing together and becoming small and smooth

Question 4

Solution

Answer 4

is a process where water dissolves minerals from rocks and carries them along

Question 5

Weathering types

Answer 5

Carbonation (breakdown of rock by changing the chemical composition e.g acid rain)
Mechanical (breakdown of rock without changing the chemical composition e.g freeze thaw)
Biological (animals / plants weakening rock by burying and roots)

Question 6

What happens in the transportation method : solution

Answer 6

Smallest particles are dissolved and transported within the water

Question 7

What happens in the transportation method: traction

Answer 7

Large sediment is rolled along the river bed

Question 8

What happens in the transportation method: saltation

Answer 8

Forms from attrition and bounces along the bed

Question 9

What happens in the transportation method: suspension

Answer 9

Small sediment is suspended through the water.
