Question 1

Explain how geology and lithology alters coastal landforms (8 marks)

Answer 1

The geology of a coastline can alter coastal landforms as it impacts what landforms occur and how they change over time. The geology of a coastline can be whether it is discordant or concordant. This alters ho

Question 2

Explain the formation of headlands and bays (8 marks)

Answer 2

Headlands and bays are erosional landforms which are found at discordant coastlines. Discordant coastlines are when layers of rock run perpendicular to the coast. Softer rock/clay is eroded faster then indigenous hard rock (chalk). This creates a outward facing area of land which is known as a headland and a bay where the softer rock is eroded faster. Over time at the headland it may form a cave which develops into an arch, stack and eventually stump due a weakness in the headland.
An example of a headland is at spurns head.
