by Mr Bell
Physical Environments 2
National 5 Geography
Within the context of two landscape types, selected from either:
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
3. Cave and Arches
5. Spits and Sand bars
1. I can explain how the sea erodes the landscape by the processes of:
1. Hydraulic Action
Coastal Processes of Erosion
This is the force of the waves crashing against the shore and cliffs.
This is when rocks carried by the waves are thrown against the cliffs, wearing away the coastline.
Rocks carried by the waves smash into each other, wearing each other away and creating smaller material to be used as erosion.
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
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.
