Describe a type of mass movement (2 marks) Types of mass movement rock slide
Describe a type of mass movement (2 marks) Types of mass movement - slumping
Describe a type of mass movement (2 marks) Types of mass movement rock fall
Headlands and Bays Which rock is the hard rock and which is the soft rock? How do you know this?
Explain the processes which lead to the formation of headlands and bays (4 marks) Explain how geology can affect the shape of the coast line (4 marks)
BAY HEADLAND
Wave Cut Platforms The land left at the foot of the cliff is called a wave cut platform. Wave cut platform
Explain the processes which lead to the formation of wave cut platforms (4 marks) Explain why cliffs retreat (4 marks) Wave cut platform animation
Explain the processes which lead to the formation of wave cut platforms (4 marks) Explain why cliffs retreat (4 marks)
Caves, stacks and arches Some of the coastlines most striking scenery is caused by the formation of caves, arches and stacks The sea attacks the foot of the cliff and erodes the areas of weakness ( cracks ) The crack gets larger and develops into a small cave
The cave is widened and deepened until it cuts through the headland to from an arch The arch is continually eroded until it eventually collapses. This leaves part of the cliff detached on its own ( a stack ). Erosion continues until the stack is worn down to a stump
Explain the processes which lead to the formation of a stack (4 marks) The formation of a stack animation
Explain the processes which lead to the formation of a stack (4 marks)
Recap quiz name the features 2 1 4 3 5
Describe 2 process of sediment transpiration by the sea (4 marks) Types of transportation Constructive waves form features of deposition due to their weak backwash
Explain the process of longshore drift (4 marks) Explain the processes that lead to the formation of beaches (4 marks) Longshore drift http://www.bbc.co.u k/education/clips/z6 jb4wx
Explain the process which lead to the formation of spits (4 marks) The formation of spits
What is a bar? If a spit joins one part of the mainland to another it is called a bar. For example, there is a bar at Orford Ness in Devon.
Explain the process which lead to the formation of bars / tombolos (4 marks) The formation of bars The formation of tombolos
Explain the process which lead to the formation of bars / tombolos (4 marks) The formation of sand dunes
