Mass Movement
Science Weather & Erosion Unit S6E3
| Question | Answer |
|---|---|
| Process of natural forces moving weathered rock and soil? | Erosion |
| Material moved by erosion, including pieces of rock or soil or dead plants or animals? | Sediment |
| When erosion drops or lays down sediment? | Deposition |
| When gravity moves sediment downhill? | Mass Movement |
| Four (4) types of mass movement? | 1)Landslides, 2)Mud flows, 3)Slump, 4)Creep |
| Mass movement that is the most destructive? | Landslide |
| Mass movement when water, rock and soil move downhill rapidly? | Mudflow |
| Mass movement in which mass of rock and soil suddenly slip down a slope? | Slump |
| Mass movement that is very slow? | Creep |
| Major agent of erosion that has shaped Earth's land surface? | Water erosion / Runoff |
| What is the process of runoff over time? | 1)Rills & Gullies, that get bigger and make 2)Streams and Rivers, that get bigger and make 3)Tributaries |
| Runoff that makes tiny grooves in the soil that grow larger forming gullies? | Rills & Gullies |
| Runoff that makes gullies join together to form a larger channel called a stream? | Streams & Rivers |
| Runoff that makes streams grow together by getting more and more water and then form a tributary; for example, Missouri & Ohio Rivers are tributaries of the Mississippi River? | Tributaries |
