main features of coastal transport and deposition

Question 1

TRANSPORT traction

Answer 1

rolled along the sea bed

Question 2

TRANSPORT saltation

Answer 2

bounced along the sea bed

Question 3

TRANSPORT suspension

Answer 3

small particles carried by waves

Question 4

TRANSPORT solution

Answer 4

dissolved chemicals in the water, chemical change (limestone and chalk)

Question 5

swash

Answer 5

body of water pushing up the beach after a wave has broken

Question 6

backwash

Answer 6

body of water pushing down the beach after wave reaches highest point

Question 7

fetch

Answer 7

length uninterrupted water over which waves can be generated

Question 8

how are waves formed?

Answer 8

wind blows over ocean waves-friction occurs- energy=waves. stronger winds=greater friction

Question 9

constructive waves

Answer 9

long and wave height <1m -breaking waves low levels of energy and spill onto beach-swash quickly absorbed by beach- sediment thrown increases by breaking waves accumulates in ridges/berms. backwash has little power to move sediment=beach!
