How are headlands and bays changing overtime?

Headlands and bays are formed by which process?

• Erosion of alternating hard and soft rock along the coastline

• Deposition of sand by wind

• Volcanic activity near the coast

• Movement of tectonic plates

Write the definition for the key term: Hydraulic power.

• Hydraulic power is the force of water hitting the cliffs and compressing air into cracks, causing the rock to break apart.

• Hydraulic power is the process of wind eroding rocks and transporting sediment.

• Hydraulic power is the chemical reaction between rainwater and minerals in the rock, leading to decomposition.

• Hydraulic power is the movement of glaciers scraping and grinding the earth's surface.

Write the definition for the key term: Abrasion.

• Abrasion is the process by which waves pick up rocks and pebbles and hurl them against the cliff face, wearing it away.

• Abrasion is the process by which plants grow on rocks and break them apart.

• Abrasion is the process by which wind deposits sand in new locations.

• Abrasion is the process by which rainwater dissolves minerals in rocks.

The part of the cliff that will be eroded by the sea is:

• the base of the cliff

• the top of the cliff

• the middle of the cliff

• the land behind the cliff

The cliff will slowly move backwards because:

• waves erode the base of the cliff over time.

• plants grow on the cliff and push it back.

• the sun heats the cliff and causes it to crack.

• animals dig holes in the cliff.

Number the statements to explain the formation of a wave cut platform:

• 1, 2, 3, 4, 5, 6

• 6, 5, 4, 3, 2, 1

• 2, 1, 4, 3, 6, 5

• 3, 1, 2, 5, 4, 6

A diagram can be used to explain how a wave cut platform is formed.

• True

• False

• It is not possible to use a diagram

• A diagram is only used for mountains

Arrange the statements in the correct order.

• 2

• The base of a cliff is eroded by hydraulic power and abrasion.

• 3

• A wave cut notch is formed.

• 5

• Overtime the wave cut notch will erode deeper and deeper into the cliff.

• 1

• Eventually the top of the cliff collapses as there is nothing to support it.

• 4

• Hydraulic power is the force of the water breaking up the cliff. Abrasion is the process of rocks in the water banging against the cliff and breaking it.

What is a 'cave' in coastal geography? Fill in the blank: A cave is a ________ formed when waves erode a crack in the cliff.

• hollow area or chamber

• solid rock formation

• sand dune

• coral reef

What is a 'stack' in coastal geography? Fill in the blank: A stack is a ________ left standing in the sea after an arch collapses.

• pillar of rock

• sand dune

• coral reef

• mudflat
