COASTAL LANDSCAPES
Landscape types

Within the context of two landscape types, selected from either: 

Glaciated uplands and Coastal landscapes OR
Upland limestone and Rivers and their valleys 

The identification and formation of the following landscape features: 

1. COASTAL LANDSCAPES

The formation of the following landscape features:

1. Headlands and Bays
2. Cliffs
3. Cave and Arches
4. Stacks
5. Spits and Sand bars
COASTAL PROCESSES
1. I can explain how the sea erodes the landscape by the processes of:

1. Hydraulic Action
2. Abrasion
3. Attrition
4. Solution
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
Longshore Drift

When 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.
