Coast

A narrow strip between land and sea

Name the 4 processes of coastal erosion

Hydraulic Action


Corrasion/Abrasion


Corrosion


Attrition

Hydraulic Action

The pressure of water being thrown against the cliff by waves.




(Hydraulic Pressure)Water compresses air into cracks in rocks breaking the rocks apart

Corrasion/Abrasion

Sand & Pebbles carried in the waves are thrown against the cliff causing errosion

Corrasion

Chemical reaction between some rocks and the salty sea water.


The water dissolves the rock away.

Attrition

Wearing away of pebbles on the shore.


As waves move in/out pebbles hit into one another.


This chips pieces off and makes them smaller and smoother.

4 processes of transport

Traction


Saltation


Suspension


Solution

Traction

Large pebbles role along the sea floor

Saltation

Small sand size particles bounce along the sea bed

Suspension

Small clay sized particles are floated in the water

Solution

Materials dissolved in water are carried

3 types of mass movement

Rock falls


Land slumping


Soil Creep

3 types of weathering

Exfoliation


Solution Weathering


Biological Weathering

Exfoliation

In the day when temperatures are high rocks heat up and expand


At night in cooler temperature rock contracts


Over time this causes the outer layer of rock to fall off

Solution Weathering

Rain water containing weak acid reacts with certain rocks like limestone/chalk


The acid in rainwater dissolve away the rocks and it is carried away in solution

Biological Weathering

Plants and animals cause the break up of rock.


When seeds fall in gaps in rocks and plants force there way through rocks causing them to crack.


Burrowing animals can also add to this type of Weathering.
