Transportation and Mass Movement

Question 1

4 main transportation processes

Answer 1

Traction
Saltation
Suspension
Solution

Question 2

Define traction

Answer 2

Sediment rolls along sea bed, pushed by waves and currents

Question 3

Define saltation

Answer 3

Sediment bounces along sea bed due to force of water and wind

Question 4

Define suspension

Answer 4

Sediment carried in water column

Question 5

Define solution

Answer 5

Dissolved material carried on water as a solution

Question 6

What is mass movement?

Answer 6

The movement of rock downhill due to gravity

Question 7

How do weathering and mass movement work together?

Answer 7

Cliffs are weakened by weathering, loose pieces eventually fall

Question 8

What are the 3 main forms of mass movement

Answer 8

Rock fall
Landslide (rock slide)
Slumping

Question 9

Explain rock fall

Answer 9

Rapid fall of rock down steep cliff
Fragments break due to gravity
Bare rocks are exposed to erosional processes

Question 10

Explain landslide (rock slide)

Answer 10

Sudden fall of large amount of rock (linear direction)

Mass remains together until reaches floor

Question 11

Explain slump

Answer 11

Movement of rocks down a rotational slide, after heavy period of rain
Rock on top becomes heavier
