Processes of Erosion
Waves crash against cliff face and compresses air into the cracks, putting pressure on
the rock in which the rock eventually cracks.
De-structive waves hurl pebbles and other material at the cliff face which remove
small particles from the cliff.
Eroded particles in the water smash into each other and break into smaller fragments
and are smooth and rounded.
Weak carbonic acid in the sea water dissolves rock such as chalk and limestone.…read more
Processes of Transportation
Large boulders are pushed along the sea bed by the force of the water.
Pebble sized particles are bounced along the sea bed by the force of the water.
Small particles like silt and clay are carried along in the water column.
Soluble materials dissolve in the water and are carried along by the sea.…read more
Occurs when temperatures alternate above and below 0°C , and water gets into a rock
with cracks e.g. Granite. When the water freezes the rock expands by 9% which
puts pressure on the rock. When the water thaws it contracts and the pressure on
the rock is released. Repeated freezing and thawing widens the crack and causes
the rock to break up.
When the coastline comes in contact with acid from the rain and salt from the
seawater it creates carbonic acid which then causes the rock to react with it results
in rocks breaking down.…read more
