Mass Movement
These flashcards will give you information on mass movement/causes.
Term | Definition |
---|---|
Mass Movement | One of the several processes that move sediment downhill. |
Mass Movement examples | Landslides, mudslides, slump and creep. |
Sediment | The material moved by erosion or Earths materials deposited by erosion. |
Deposition | The process in which the forces of Erosion move the sediment in new places. |
Erosion | The process by which water, ice, wind or gravity moves weathered rock and soil. |
Landslide (Example of Mass Movement) | 1. Most destructive kind of mass movement. 2.Occurs when rock/soil slide quickly down a slope. |
Slump (Example of Mass Movement) | 1.Has a mass of rock/soil that slips down a slope in one large mass. 2.It often occurs when water soaks the base of a mass of soil in a normally dry area. 3. Can look like a giant spoon scooped soil from a hillside. |
Mudflow/Mudslide (Example of Mass Movement) | 1. Rapid downhill movement of a mixture of water, rock and soil. 2. Water can be 60% of the mudslidw 3.Often occurs after heavy rains in a normally dry area. 4.Under conditions, clay can turn to liquid and flow 5.Earthquakes can trigger mudslides and |

Creep (Example of Mass Movement) | 1. It's a very slow downhill movement of rock and soil. 2. Can occur on gentle slopes. 3. Tilts objects-(ex.telephone poles, gravestones, fence posts) at a spooky angle 4. Often results from freezing/thawing of water in cracked layers of rock beneath th |
