//Mass Movemebt

Question 1

What allows mass movement to happen

Answer 1

• Steep Slopes
• Heavy rainfall =wet regolith
• vegetation (roots bind soil)

Question 2

Soil creep

Answer 2

-Downslope movement of soil under the influence of gravity
Results: poles, fences tilt, road cracks, bent trees
Effects: free-thaw, deforestation, human interference, animals
-Gentle slop/slow

Question 3

Mudflows and Bogbursts

Answer 3

• Bogbursts: If rainwater cannot drain/soak, peat can be heavy/ saturated
• Mudflows: Saturated regolith rapidly flows down slopes
• Gentle slope/slow-rapid

Question 4

Landslide

Answer 4

-Landslide: anything that undercuts base of slope,
Effects: sea erosion, road building, quarrying
Very steep slope/very rapid

Question 5

Influences of mass movement

Answer 5

Precipitation: water makes regolith heavier, letting it move easily and quickly down the slope
Gradient: steeper the slope, mass movement will occur more often
