Flashcards in Mass Movement Deck (9):
1

Process

Is know as mass movement it can be fast or slow

2

Gradient

How steep is the slope? The steeper the slope = faster movement

3

Water content

Makes regolith heavier, faster acts as a lubricant so heavy rainfall can speed up mass movement

4

Human activity

Building roads or quarrying in upland areas can make land unstable

5

Vegetation

Roots of plants or trees can help prevent mass movement

6

Animals

Burrowing animals or overgrazing can make a slope unstable

7

Types of mass movement::
SLOW

Soil creep

8

Types of mass movement::
FAST

Bog bursts
Mud flows
Landslides
Avalanches



























9

Regolith

Loose material produced when rocks are weathered and eroded. When formed in upland areas gravity causes it to move down slope
