coastal processes and waves

Question 1

what is deposition

Answer 1

when the water looses energy it drops the rock particles it has been transporting

Question 2

explain traction

Answer 2

large sediment are rolled along the sea bed

Question 3

explain solution

Answer 3

salt and acid dissolve the rocks on the land

Question 4

explain saltation

Answer 4

sediment is bounced along the sea bed

Question 5

explain suspension

Answer 5

small particles carried by the water can make it look cloudy

Question 6

explain long shore drift

Answer 6

zig-zag movement of material along the beach determined by the dominant wind direction

Question 7

what causes waves

Answer 7

wind blowing over the surface of the sea creates friction so energy is transferred

Question 8

what things determine the size of waves

Answer 8

how strong wind is, length of fetch, how long wind has been blowing

Question 9

what is fetch

Answer 9

maximum distance of open water over which the wind can blow longer fetch mans larger wave

Question 10

what is swash

Answer 10

waves moving up the beach at an angle

Question 11

what is backwash

Answer 11

waves coming straight back down the beach under the influence of gravity

Question 12

what characteristics do constructive waves have

Answer 12

low height+frequency,strong swash,weak backwash

Question 13

what characteristics do destructive waves have

Answer 13

large height+frequency,strong backwash,weak swash
