3.3 Coastal Landforms

Question 1

Name 8 landforms that are caused by erosion

Answer 1

cliffs 
wave cut platforms
headlands
bays 
caves
arches 
stacks
stumps

Question 2

Formation of cliffs

Answer 2

they form as the sea erodes the land

over time, the cliffs retreat due to the action of waves and weathering

Question 3

Formation of wave cut platforms

Answer 3

weathering and wave erosion cause a notch to form at the high water mark- this developed into a cave
the rock above becomes unstable with nothing to support it and it collapses
this creates a wave cut platform which are flat surfaces left behind when a cliff is eroded

Question 4

Example of a cliff and wave cut notch platform

Answer 4

Lannacombe Bay in South Devon

Question 5

Formation of headlands and bays

Answer 5

the soft rock is eroded quicker than the hard rock, this forms bays and headlands

Question 6
