Sediment and Transportation

Question 1

what are the four sources of shingle?

Answer 1

• Rivers: Fine grains, Silts and sands
• Cliffs: usually course sand and shingle is produced
• The sea: The tides move the sediment
• Glaciers and ice sheets

Question 2

which type of wave pushes material up the beach?

Answer 2

constructive

Question 3

which type of wave removes material from the beach?

Answer 3

destructive

Question 4

what is traction?

Answer 4

when the largest cobbles and pebbles are rolled along the sea bed. A lack of energy from the waves mean that they cannot be picked up.

Question 5

what is is saltation?

Answer 5

when smaller pebbles bounce along te sea bed. this is due to the changes in wave energy and the pebbles bouncing into other pebbles

Question 6

what is suspension?

Answer 6

fine sands are held in the body of water and move with the current

Question 7

what is solution

Answer 7

Microscopic material- dissolved in the sea water and is carried within the moving currents

Question 8

what are the four processes in a sediment cell?

Answer 8

inputs, outputs, deposition and transportation

Question 9

what are sediment cells separated by?

Answer 9

protruding land

Question 10

what is sediment source?

Answer 10

material is collected on the coast from different places-rivers, sea beds, eroded coasts

Question 11

what is a sediment cell?

Answer 11

distinct areas of coast, separated by deep water or headlands within which material is moved but contained within that cell

Question 12

what is a sediment sink?

Answer 12

areas where sediment is deposited

Question 13

when does the material sink?

Answer 13

when the energy of the water decreases eg. wave refraction because bays have calmer water

Question 14

how many sediment cells are there around england and wales?

Answer 14

11
