Mass Movement

Question 1

Regolith

Answer 1

Loose material produced when rocks are weathered and eroded

Question 2

Mass movement

Answer 2

The movement of material down a slope

Question 3

Process

Answer 3

Is known as mass movement

Question 4

Name the factors affecting mass movement

Answer 4

Gradient
Water content
Human activity
Vegetation
Animals

Question 5

Gradient

Answer 5

Refers to the steepness of the slope

Question 6

Water content

Answer 6

Makes the regolith heavier which makes it move faster, rain can also speed up mass movements movement

Question 7

Human activity

Answer 7

Building roads or quarrying in upland areas can make land unstable which causes mass movement

Question 8

Vegetation

Answer 8

Roots of plants and trees keep soil stable which prevents mass movement

Question 9

Animals

Answer 9

Burrowing animals, overgrazing can make land unstable

Question 10

What is soil creep

Answer 10

Movement of soil down a slope due to gravity, it is the slowest form of mass movement e.g. Fences and poles tile. Cracks in walls

Question 11

Boy bursts

Answer 11

Mass of a bog or peat moves down slope. Harvey rainfall causes peat to become saturated which causes it to move downslope (mudflow)

Question 12

Name an example of a dangerous mudflow

Answer 12

Laher
