Term
| landslide--definition & cause |
|
Definition
When rock & soil SLIDE rapidly down a steep slope.
Caused by cutting into a slope or by an earthquake |
|
|
Term
| slump--definition & cause |
|
Definition
When mass of rock & soil SLIPS.
Caused by water soaking the bottom of soil that is rich in clay. |
|
|
Term
| creep--definition & cause |
|
Definition
A SLOW downhill movement of rock & soil
Caused by freezing & thawing in the rock below |
|
|
Term
| mudflow--definition & cause |
|
Definition
The rapid downhill movement of a mixture of water, rock, & soil.
Occurs after heavy rain in a normally dry area. Can be triggered by an earthquake. |

|
Term
| Processes of mass movement - what is the cause of each? |
|
Definition
- creep- freezing and thawing of water in cracked layers
- slump- when water soaks the bottom of soil that is rich in clay
- mudflow-earthquakes
- landslide- where road builders have cut highways through hills or mountains
