COASTAL PROCESSES
1. I can explain how the sea erodes the landscape by the processes of:
1. Hydraulic Action
2. Abrasion
3. Attrition

Coastal Processes of Erosion
Hydraulic Action
This is the force of the waves crashing against the shore and cliffs.
Abrasion
This is when rocks carried by the waves are thrown against the cliffs, wearing away the coastline.
Attrition
Rocks carried by the waves smash into each other, wearing each other away and creating smaller material to be used as erosion.
Solution
Chemicals in our sea water dissolve minerals in certain rocks.

COASTAL DEPOSITION PROCESSES
1. I can explain how the sea shapes the landscape by the processes of:
1. Longshore Drift

Coastal Processes of Deposition Loading...
Longshore DriftWhen the wind approaches the beach at an angle the waves (swash)
transport sand up the beach at that angle.
Gravity pulls waves (backwash) down the beach at 90°
Over time the many waves cause sand particles to move along the beach.

1. Headlands & Bays
1. Description: When there are alternate bands of hard and soft rock in contact with the sea.
2. Formation: The sea erodes the soft rock more quickly forming a Bay; and leaving the hard rock jutting out as a Headland.
3. Process: By hydraulic action the force of the waves crashing against the shore and cliffs.
4. Process: And by abrasion when rocks carried by the waves are thrown against the cliffs, wearing away the coastline.

4. Process: And by abrasion when rocks carried by the waves are thrown against the cliffs, wearing away the coastline.
2. Cliffs
1. Description: Cliffs form when there is harder, resistant rock.
2. Formation: The power of the wave is greatest where it hits the base of the cliff.
3. Process: By hydraulic action the force of the waves crashing against the shore and cliffs.
4. Process: And by abrasion when rocks carried by the waves are thrown against the cliffs, wearing away the coastline.

4. Process: And by abrasion when rocks carried by the waves are thrown against the cliffs, wearing away the coastline.
3. Caves & Arches
1.Formation: Waves attack a line of weakness in the headland to form a cave.
2. Formation: When erosion breaks though the headland an arch is formed
3. Process: By hydraulic action the force of the waves crashing against the shore and cliffs.

Choose from features: cliff; headland; bay; stack.
Explain the formation of one of the coastal features listed above.
You may use a diagram(s) in your answer.

4. Stack
1. Description: A free-standing piece of rock called a stack which is separate from the headland.
2. Formation: Waves attack a line of weakness in the headland, developing into a cave and the arch, continuous erosion will cause the roof of the arch to collapse.
3. Process: By hydraulic action the force of the waves crashing against the shore and cliffs.
