WEEK 2 - erosional landforms Flashcards
1
Q
How are waves created?
A
by wind blowing over the sea, The friction from the wind causes the surface water to
move in ripples which eventually form full waves.
2
Q
what are destructive waves like?
A
tall, stormy waves. The backwash is strongest, so the beach sediment is removed,
and erosion occurs.
3
Q
what are constructive waves like?
A
smaller, flatter waves. The swash is stronger than
the backwash, so the beach is built up.
4
Q
How do headlands and bays form?
A
. If there are alternating bands of hard and soft rock perpendicular to the coast, the soft rock will erode faster

when eroded further becomes an arch, then stack and then stump
