Coasts - Deposition/Transportation Processes Flashcards
1
Q
What are the deposition/transportation processes?
A
- deposition
- longshore drift
- traction
- saltation
- solution
- suspension
2
Q
Describe suspension
A
Small sediment is carried with the flow of the water
3
Q
Describe traction
A
- heavier sediment is rolled along the seadbed
4
Q
Describe saltation
A
Smaller sediment bounces along the seabed
5
Q
Describe solution
A
- dissolved sediment is carried in the water
6
Q
Describe longshore/littoral drift
A
- 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
7
Q
Describe deposition
A
- waves lose energy and can no longer carry the sediment, so it gets deposited
