Sediment sources

Question 1

Rivers

Answer 1

accounts for vast majority of coastal sediment, especially in high rainfall environments

Sediment will be deposited in mouths and estuaries where it will be reworked by waves, tides and currents

Question 2

Cliff erosion

Answer 2

Extremely important locally in areas of relatively soft or unconsolidated rock
EG Holderness coast, rates of erosion can be as high as 10m/year

Question 3

Longshore drift

Answer 3

Sediment is transported from one stretch to another

Question 4

Glaciers

Answer 4

sediment trapped within ice released into sea

Question 5

Offshore

Answer 5

Can be transferred into coastal zine by waves, tides and currents
Storm surges associated with tropical cyclones can be responsible for inputs of sediment
