Question 5

most coastlines will have a

Answer 5

prevailing wind direction

Question 6

the prevailing wind controls

Answer 6

Answer 8

frictional drag

Question 9

the energy acquired by waves depends on: (3 items)

Answer 9

• fetch
• wind strength
• length of time the wind blows for

Question 10

wind acts as an agent of erosion because

Answer 10

it can pick up and remove sediment from the coast, which is then used to erode other features

Question 11

abrasion is when

Answer 11

material picked up by the wind is used to erode other features by the wearing out of landscape features
