Component 2 - The UK's evolving physical landscape

Question 1

What are the features of soft rock?

Answer 1

Soft rock are more easily eroded
Cliffs are less rugged and less steep than hard rock coasts
Soft rock landscapes include bays

Question 2

What are the features of hard rock?

Answer 2

Hard rock is resistant to all types of erosion
Cliffs are high, steep and less rugged
Hard rock landscapes include wave cut platforms and headlands

Question 3

What are concordant coasts?

Answer 3

Concordant coasts are made up of the same rock type, parallel to the sea

Question 4

What are discordant coasts?

Answer 4

Discodant coasts are made up of alternating rock types in layers, perpendicular to the sea

Question 5

What factors affect rate of erosion?

Answer 5

Factors which affect the rate of erosion include:
Geological structure
Wave climate
Local currents and tidal energy
Ground water levels

Question 6

How are headlands and bays formed?

Answer 6

Headlands and bays are formed when water erodes the soft rock in a cliff forming bays, and headlands are formed when the hard rock sticks out from the cliff due its resistance to erosion
