sediment cells

Question 1

What is a sediment cell?

Answer 1

A stretch of coastline bordered by 2 prominent headlands where the movement of sediment is contained.

Question 2

Theoretically what type of systems are Sediment cells?

Answer 2

Closed - only energy can enter and exit

Question 3

In reality what type of systems are Sediment cells?

Answer 3

Open- sediment can sometimes leave depending on the boundary (due to wave refraction)

Question 4

What are some inputs to sediment cells?

Answer 4

Sediment that falls from cliffs, fluvial inputs, erosion of offshore bars.

Question 5

What are some stores of sediment cells?

Answer 5

Bars, Banks, Beaches, Dunes.

Question 6

What are some transfers of sediment cells?

Answer 6

Littoral drift, rip currents

Question 7

What does each major sediment cell break into?

Answer 7

Sub cells

Question 8

What happens in subcells?

Answer 8

The same as the bigger cell, just on a smaller scale. All the marine processes - deposition, erosion, transportation interlink.
