Mass Movement Flashcards
1
Q
What is Mass Movement?
A
Is it the movement of material downslope under the influence of gravity.The loose material is called regolith.
2
Q
What are the factors that affect mass movement?
A
Gradient (slopes)
Vegetation
Human Activity
Water content
3
Q
Categories of mass movement
A
Slow:Soil creep
Fast:Landslide,Avalanche,Bogburst,Mudflow
4
Q
Types of mass movement
A
Soil creep
Landslides
Bogburst
Mudflow
5
Q
Gradient (slope)
A
The steeper the slope the faster the mass movement.
6
Q
Vegetation
A
It slows down mass movement,as the roots of plants bind the soil.
7
Q
Human Activity
A
It can speed up the rate of mass movement by undercutting hillsides for road building.
8
Q
Water content
A
This can speed up mass movement by loosening the regolith.
