WEEK 2 - erosional landforms

Question 1

How are waves created?

Answer 1

by wind blowing over the sea, The friction from the wind causes the surface water to
move in ripples which eventually form full waves.

Question 2

what are destructive waves like?

Answer 2

and erosion occurs.

Question 3

what are constructive waves like?

Answer 3

the backwash, so the beach is built up.

Question 4

How do headlands and bays form?

Answer 4

. If there are alternating bands of hard and soft rock perpendicular to the coast, the soft rock will erode faster
forming headlands and bays. Overtime, a crack in a headland can be eroded to form a cave, which
when eroded further becomes an arch, then stack and then stump
