Weathering
Vocab Focus On Earth Science Chpt 3
| Question | Answer |
|---|---|
| erosion | the process by which natural forces move weathered rock and soil from one place to another. |
| deposition | when eroded rock and soil stop moving and lay down on the surface of the land or the bottom of lakes, rivers, and oceans |
| gravity | the primary force of erosion that moves rock and soil downhill |
| deposit | the root word of deposition |
| runoff | the moving water from rain and melted snow that moves over the earth's surface and is a primary force of erosion |
| sediment | the material moved by erosion, usualty weathered rock and soil |
| rills | tiny channels or grooves in the soil caused by rain runoff moving downhill because of gravity and flooding. |
| longshore drift | this two word phrase occurs when waves come into shore at an angle, helping to push sediment down the coast. |
| delta | the place where a river flows into an ocean or lake and deposits lots of sediment as the river slows down |
| river | the largest channel of runnoff water, when several streams flow together |
| gully | a large groove in the soil caused by many rills carrying rain water after a strong rain |
| meandering | this word describes the curvy path of a river in a flat flood plain |
| flood plain | the flat area around a river that gets flooded after huge rains bring runoff downstrearn |
| stream | a large channel of rainwater running downhill that is formed from many gullies flowing together |
| small -> big: rills, gullies, streams, rivers | the order, from smallest to biggest, of runoff channels |
| channels | A depressed area in the soil where runoff rain water can travel. These can be small (rills) or huge (rivers). |
| beach | An area of wave-washed sediment along a coast. |
| creep | A type of mass movement where the surface slowly slides down a steep hill. |
| waves | The key agent of erosion along beaches. |
| V-shaped valley | Over a long period of time, fast-flowing downhill rivers can form a _-______ _______ |
| spit | When part of a beach projects like a finger out into the water of the incoming ocean. lt's kind of like a connected sandbar. |
