Mass Movement (coasts) Flashcards
1
Q
define: Mass Movement
(rock fall, landslide, mudflow, rotational slip/slump)
A
the downward movement or sliding of material under the influence of gravity
2
Q
Rockfall
A
fractions of rock break away from the cliff face often due to freeze-thaw weathering called scree
3
Q
Landslide
A
blocks of rock slide downhill
4
Q
Mudflow
A
saturated soil and weak rock flows down a slope.
-usually with a stream nearby
-the slide creates a ‘lobe’ (like an ear) at the bottom
5
Q
Rotational slip/slump
A
saturated soil and weak rock slump down a curved surface (like a wiggly slide)
