what is abrasion
rocks and sediment are thrown against the cliffs by waves and causes parts of the cliff to break off

what is corrosion
chemicals and water dissolve soluble rocks such as limestone and chalk

what is attrition
rocks in the water smash against each other and get broken down into smaller pieces

what is hydraulic action
air in gaps are compressed when water enters and the pressure causes the rock to expand and break off

what are 4 methods of transportation in a coast
traction, solution, saltation, suspension
saltation=?
sediment is bounced along the sea bed by the force of the water
sediment is bounced along the sea bed by the force of the water
saltation
traction=?
very large particles are rolled along and pushed along the sea bed by the force of the wave

traction
what is deposition
material being transported is dropped off due to lack of energy
