Mass Movement Landforms Flashcards
Mass movement creates distinctive landforms including
Rotational scars
Talus scree slopes
Terraced cliff profiles
A rotational scar is:
Curved
Un-weathered
Un-vegetated
Forms as a result of rotational slumping
The section that has detached is at the base of the cliff often with vegetation attached
Talus scree slope
A talus scree slope is a
fan-shaped mound of material
Made of block-fall debris which has accumulated at the foot of a cliff
Often, they have a concave profile
Terraced cliff profile
The profile of the cliff is
stepped
This is the result of the lithology or fractures in the rock
t is important to remember that subaerial processes and the processes which occur at the foot of the cliff (erosion, transportation and deposition) work together to influence the recession rates.
