Landforms of erosion and weathering

Cards (16)

What is mass movement?
Downhill movement of material due to gravity
What are the main types of mass movement
Slumping , landslide , rockfall
Where does and why landslide occur ?
Rain water repeatedly seeps into porus rock putting pressure on the straight line of weakness
Where does slumping occur
Curved line of weakness
What is rockfall 
Collected rocks at the bottom of cliff known as a scree slope
What is a wave cut platform
Flat area of rock at the base of a cliff
What is a wave cut notch
An indentation in the cliff face creating an overhanging cliff
What is a headland
A cliff that sticks out into the sea
What is a bay?
A crescent indentation in the coastline
Why do beaches form in a bay 
They are sheltered as a result waves lose their energy depositing material
where Is a headland and bay formed ?
Along a discordant coastline where hard and soft rock erode at different rates=differential erosion
What is a cave arch stack stump
A coastal landform created along a headland
How is a cave formed
When erosion(hydraulic action and abrasion) widen the line of weakness along a headland
How is an arch formed
Continued erosion erode the back of the cave
How is a stack formed
Weathering(such as freeze thaw) weakens the top of an arch causing it to collapse leaving a stack
How is a stump formed
When waves erode the base of the stack and weathering the top
