SUSPENSION, SALTATION, TRACTION, SOLUTION.

Question 1

What is the objective of the lesson?

Answer 1

To understand how sediment is moved and deposited along the coastline

Question 2

What are the four main processes of sediment transport?

Answer 2

• Suspension
• Saltation
• Traction
• Solution

Question 3

What is suspension in sediment transport?

Answer 3

Small particles are carried in the water and can make it look cloudy

Question 4

Define saltation in the context of sediment transport.

Answer 4

The load is bounced along the sea bed, as currents cannot keep the larger and heavier material afloat for long periods

Question 5

What does traction refer to in sediment movement?

Answer 5

Pebbles and larger sediments are dragged along the sea bed by the waves as they are too heavy to be carried

Question 6

Explain the process of solution in sediment transport.

Answer 6

Minerals are dissolved in the sea water and carried in solution

Question 7

What factors influence the movement of sediment along the coastline?

Answer 7

• The power of the waves
• The wind
• The angle and direction of the longshore current
• Continual swash and backwash

Question 8

What happens during deposition?

Answer 8

Deposition occurs when sediments are set down as currents slow due to frictional forces or other counter currents

Question 9

Fill in the blank: Sediments are deposited when currents _______.

Answer 9

slow down
