fetch (distance waves travelled), strength of wave, duration wind has been blowing
2 of 12
what are the two types of waves? (not longitudinal/transverse - that's physics)
constructive and destructive

what's a swash???
when a wave reaches the shore, the water that rushes up beach = swash (water that breaks up a beach)
4 of 12
what's the name of the water that then flows back down the beach?
backwash
5 of 12
The energy of the swash and backwash determine the type of wave. a destructive wave (removes/adds?) material to the beach
removed
6 of 12
in a destructive wave the swash is (stronger/weaker?) then the backwash
weaker (strong backwash removes material - water flowing back to sea)
7 of 12
in a destructive wave, the waves are.... (steep? flat/low? far apart? close together?)
waves are steep and close together
8 of 12
describe the characteristics of a constructive wave
swash is stronger then backwash (strong swash brings sediment up beach + backwash is not strong enough to remove sediment), waves are low and far apart
9 of 12
Sediment is carried by the waves along the coastline. The movement of the material is known as ____ ___
longshore drift.
10 of 12
Waves approach the coast at an angle because of the direction of prevailing wind. The (backwash/swash?) will carry the material towards the beach at an angle.
swash
11 of 12
The backwash then flows back to the sea, down the slope of the beach. The process repeats itself along the coast in the ___ movement.
zigzag
