Processes Of Marine And Aeolian Processes.

Question 1

processes of marine and aeolian deposition?

Answer 1

sand and shingle accumulate faster then they are removed.
waves slow following breaking
water pauses at the top of swash before backwash begins
water percolates back into the sea

Question 2

what is aeolian deposition?

Answer 2

refer to the entrainment , transportation and deposition of sediment by wind.

Question 3

How wind affects the coast?

Answer 3

air moves in response to the small pressure differentials set up by the warmer land and colder sea.

Question 4

What occurs when there is a large tidal range?

Answer 4

large amounts of sand may be exposed at low tide thus providing a supply of sediment to be entrained by the wind

Question 5

What does entrained mean?

Answer 5

picked up by wind

Question 6

How is sand sized sediment transported by wind?

Answer 6

Surface creep

saltation

Question 7

What is surface creep?

Answer 7

wind rolls /slides sand grains along the surface.

Question 8

What is saltation?

Answer 8

wind is strong enough to lift the grains by 1m into airflow for 30m
