1.1.6: coastal erosional landforms

Question 1

Methods of sediment transport

4

Answer 1

traction
saltation
suspension
solution

Question 2

Traction

Answer 2

Sediment rolls or slides along the seabed

Question 3

Saltation

Answer 3

Sediment is bounced along the seabed

Question 4

Suspension

Answer 4

Small particles are held and moved in the water

Question 5

Solution

Answer 5

Material dissolves in the water and is moved by the sea

Question 6

Flocculation

Answer 6

Occurs where fresh water mixes with sea water such as in a river estuary. This causes clay particles to coagulate (combine) to form ‘flocs’ which are heavier and more likely to be deposited

Question 7

Why does deposition occur

Answer 7

When the sea energy is too low to transport sediment

Question 8

Sediment sorting

Answer 8

large sediment is deposited furthest from the sea by high energy waves and smaller material is deposited closer to the sea.

Question 9

Material/sediment closer to the sea is prone to…

Answer 9

more attrition and being eroded into smaller particles
