Coasts - Deposition/Transportation Processes

Question 1

What are the deposition/transportation processes?

Answer 1

• deposition
• longshore drift
• traction
• saltation
• solution
• suspension

Question 2

Describe suspension

Answer 2

Small sediment is carried with the flow of the water

Question 3

Describe traction

Answer 3

• heavier sediment is rolled along the seadbed

Question 4

Describe saltation

Answer 4

Smaller sediment bounces along the seabed

Question 5

Describe solution

Answer 5

• dissolved sediment is carried in the water

Question 6

Describe longshore/littoral drift

Answer 6

• prevailing wind causes waves to hit the beach at an angle
• sediment is deposited
• gravity pulls the waves back perpendicular to the beach
• moves sediment along the beach over time

Question 7

Describe deposition

Answer 7

• waves lose energy and can no longer carry the sediment, so it gets deposited
