coasts

Question 1

erosion can cause different types of landforms

Answer 1

bays, headlands, cliffs, wave-cut platforms, caves, arches, stacks and stumps

Question 2

headlands

Answer 2

Headlands are formed when the sea attacks a section of the coast with alternating bands of hard and soft rock.

Question 3

bays

Answer 3

the areas around the eroded soft rocks are called bays

Question 4

wave-cut platform

Answer 4

A wave-cut notch is formed by erosional processes such as abrasion and hydraulic action - this is a dent in the cliff usually at the level of high tide.
As the notch increases in size, the cliff becomes unstable and collapses, leading to the retreat of the cliff face.
The backwash carries away the eroded material, leaving a wave-cut platform

Question 5

constructive waves

Answer 5

strong swash and weak backwash so it deposits material onto the coast

Question 6

destructive waves

Answer 6

cause most of the erosion

stronger backwash than swash so they drag more deposited material than releasing it

Question 7

chemical weathering

Question 8

chemical weathering

Answer 8

chemical composition in rocks changes
when climate is warm and wet carbon dioxide can dissolve in rain creating carbonic acid
when this acid hits the part of the rock made of calcium carbonate it dissolves

Question 9

mass movement

Answer 9

caused by weathering erosion and gravity

mass movement is the large movement of soil and rocks down the slope of a hill and cliff

Question 10

rockfalls

Answer 10

when parts of the cliff break down and crumble down the cliff

Question 11

slides

Answer 11

when material moves down a slope in a straight line

Question 12

slumps

Answer 12

when material moves down a slope in a curve
