Mass Movement, Waves
Minerals and Rockas Part 6
| Term | Definition |
|---|---|
| Mass Movement | The pulling of rock and sediment downhill by the force of gravity (Unsorted, Angular Fragments which come out of avalances, landslides, and mudslides) |
| Gravity | The force of attraction where objects fall towards the center of the Earth |
| Friction | The rubbing of one object against another (rain weakens the force of friction gravity then pulls rock and sediment down a slope) |
| Wind | Air that is moving horizontally (wind picks up loose sediment such as sand and silts and carries them to a new location |
| Deflation | Wind readily blows away loose sediment lowering the land surface until there is no more loose sediment to erode |
| Abrasion | Wind picks up and blows smaller sediment against another surface wearing it down |
| Sand Dune | depositional feature when sand is deposited in layers or mounds (Windward Side: gentle slope, Leeward Side: Steep Slope) |
| Waves | The up and down motion of water in the ocean or lake; usually by wind |
| Long Shore Current | Ocean current that flows parallel and close to the shore |
