Talus Slopes

Answer 1

Larger boulders at core with smaller material on top

Larger the fragments the steeper the cliff (due to friction between rocks)

Caused by rock falls

Question 2

Block slides

Answer 2

Material tends to stay together in large sizes, leaves a clean scar

Caused by translational slide

Question 3

Rotational slumps

Answer 3

Vegetation layer often remains intact to hold slumped material, forming a series of ‘steps’

Caused by rotational slumping

Question 4

Mudflows

Answer 4

Often occurs when water is channeled to saturate the soil

Caused by flow
