Landforms of erosion

Wave-cut platform Cliffs and wave-cut platform

Caves, arches, stacks and stumps

Caves, arches, stacks and stamps When caves are formed on both sides of a headland, their back

join and an arch is formed. The sea continues to erode the bottom of the arch. Weathering also take

place on the bare rock faces. As the sea undercuts the bottom of the arch, a wave-cut notch will form.

The arch will collapse, in time, as it is pulled down by the pressure of its own weight and gravity. This leaves behind a column of rock not attached to the headland, called a stack.

Continued wave erosion and weathering will lead to the formation of a stump that is only visible at low tide.

How to answer 6 mark questions (GCSE)?

The questions are level marked. This means that the detail of your answer counts rather than

making 6 separate points. Level 1 answers

1/2 marks out of 6 The answer is BASIC It contains descriptions rather than

explanations It does not contain case study examples

Level 2 answers 3/4 marks out of 6 The answer is CLEAR

It contains descriptions and some explanations It does contain case study examples in a basic way. It may not include statistics (data).

Level 3 answers 5/6 marks out of 6

The answer is DETAILED It contains descriptions and thorough explanations It contains case study examples and uses data to

GCSE Geography Unit 2: Coastal Landforms of erosion

Explain how geology affects the formation of coastal landforms of erosion. (6)

Movement of sediment along the coast Longshore drift

Impacts of longshore drift

What is an estuary? What is dredging?

to remove material from the bottom of the sea or a river . Landforms of deposition

(constructive waves) Beaches

Sandy beach

Durdle Door : a shingle beach separated by the famous door Dorset UK

Seaside resorts often build groynes to keep beaches in place and to reduce the effects of longshore drift

On the land side, silt and alluvium are deposited and salt marshes form.

Bars
