Mass Movement

Question 1

What is Mass Movement?

Answer 1

Is it the movement of material downslope under the influence of gravity.The loose material is called regolith.

Question 2

What are the factors that affect mass movement?

Answer 2

Gradient (slopes)
Vegetation
Human Activity
Water content

Question 3

Categories of mass movement

Answer 3

Slow:Soil creep
Fast:Landslide,Avalanche,Bogburst,Mudflow

Question 4

Types of mass movement

Answer 4

Soil creep
Landslides
Bogburst
Mudflow

Question 5

Gradient (slope)

Answer 5

The steeper the slope the faster the mass movement.

Question 6

Vegetation

Answer 6

It slows down mass movement,as the roots of plants bind the soil.

Question 7

Human Activity

Answer 7

It can speed up the rate of mass movement by undercutting hillsides for road building.

Question 8

Water content

Answer 8

This can speed up mass movement by loosening the regolith.

Question 9

How does Soil Creep occur

Answer 9

Soil Creep occurs as soil moves very slowly down gentle slopes at a speed of about 1cm per year.This is the slowest form of mass movement.We only notice its effect on the landscape from the clues it leaves after many years.
