Re-order the statements to explain how headlands and bays are formed.

• Hydraulic power and abrasion erode the coastline

• There are layers of hard and soft rock at the coastline

• The soft rock erodes first, as it is less resistant. This creates a bay.

• This leaves the hard rock sticking out as it is more resistant. This is known as a headland.

• Over time the headland will erode and the coastline will straighten.

Re-order the statements to explain how a wave cut notch and wave cut platform are created.

• The top of the cliff collapses as there is no support at the bottom.

• A wave cut notch is created.

• This process repeats and the cliff retreats.

• Over time a wave cut platform is left behind, visible at low tide.

• Hydraulic power and abrasion erode the bottom of the cliff.

Re-order the statement to explain how a spit is formed.

• A finger of sand is deposited, this is called a spit.

• A prevailing wind influences the direction of long shore drift.

• Material is moved along the coast in the direction of longshore drift until there is a change in the coast.

• A salt marsh forms behind the spit as it is a low energy zone.

• The end of the spit curves due to a secondary wind.
