3.2 - Sediment Cells

Question 1

Define inputs into sediment cells

Answer 1

Sources of the sediment which link to the processes that occur at the coast

Question 2

Examples of input processes

Answer 2

Sub-aerial weathering, e.g. attrition and abrasion , can be chemical, mechanical, or biological
Causes rock to be broken down into small particles

Question 3

Define transport

Answer 3

How sediment is moved through the cell from the site of input
E.g. wind, littoral drift, river or sea currents

Question 4

What is deposition?

Answer 4

Energy needed to carry it is reduced

Sediment is left where it is and accumulates

Question 5

Factors which affect whether the cell is open or closed

Answer 5

Coastline topography contains the cell so it can’t be transferred anywhere else
Wind can carry sediment out of the cell
