When a wave breaks, water is washed up the beach

When water runs back down the beach

What type of wave erodes the coast.

Coastal erosion

Hydraulic action.

Why can waves approach the coast at an angle??

What is the movement of transportation.

longshore drift

What are the four ways that waves and tidal currents transport sediment.

Traction

Saltation

Suspension

Minerals are dissolved in sea water and carried in solution.

One of the most important forces of change in the coastal system is?

When is Deposition likely to occur?

How are Headlands formed?

The areas where the soft rock has eroded away, next to the headland, are called ...?

What is the order of erosional land forms that take place in coastal erosion?

How is an arch formed?

How are caves created??

What type of wave helps build up beaches??

What is a spit??

2 characteristics of Hard engineering

Name 3 examples of Hard engineering?

What form of engineering option is Beach nourishment

What are Wooden barriers built at right-angles to the beach called?

Which coastal defence can protect the base of cliffs against erosion and can prevent coastal flooding?

Allowing areas of coastline to erode and then flood naturally is called:

Processes such as hydraulic action and corrasion undercut the base of a cliff to form a??

what are the processes that have caused cliff retreat?

what is mass movement

In freeze thaw weathering water turns into ice and expands. what is the percentage it expands by?

why does water turning into ice in freeze thaw weathering affect erosion?

Rain water contains what for rock to break away?

what 3 factors influence the rate of weathering??

Slumping?

Soil creep

what does CASH stand for

The more resistant rock is left sticking out into the sea. What is thid called

shallower water encourages what?

as the wave cut platform widens the rate of erosion does what??

waves refract to follow the shape of coastline and therefore focus on headlands to become ..... in bays hence beaches

what affects the direction of waves that hit the coast

sea walls reflect..
