Deposition/Erosion
Term | Definition | |
---|---|---|
Moving Water | Water that is in motion and has the ability to move (erode) and deposit sediments | |
Runoff | Precipitation that flows out over land into streams and rivers | |
River | When streams become larger and wider | |
V- Shaped Valley | Formed from erosion of a river on streams over time | |
Floodplain | An area along a river that forms from sediment deposited when the river over flows its banks | |
Delta | Form from sediment carried to the oceans by rivers | |
Alluvial Fan | A fan shaped mass of material deposited by a stream when the slope of the land decease sharply | |
Meander | The bends in the river's channel | |
Oxbow Lake | A U-shaped lake that formed when a wide meander of a river is cut off | |
Waterfall | An area where water flows over a vertical drop on a river or a stream that meets an eye that falls to lower ground | |
Glacier | Any large mass of ice that moves slowly over land | |
Valley or Alpine Glacier | A long, narrow glacier that forms when snow and ice build up high in a mountain valley | |
Continental Glacier | Is a glacier that covers much of a continent or large island | |
Plucking (Glacier) | The process in which rock fragments freeze to the bottom of a glacier and are carried when the glacier moves | |
Abrasion (Glacier) | Waves pick up sediment in shallow water and wear away (grind) the rock like sand paper | |
U-Shaped Valley | Form when a glacier erodes a river valley from its original V-shaped to a U-shaped | |
Till | Unsorted rock material that is deposited directly by a melting glacier | |
Moraine | A ridge of sediments or rocks are left behind when a glacier melts | |
Kettle | A small depression that forms when a chance of ice is left in a glacial till | |
Wave Erosion | Waves erode the sediments from cliffs and shorelines by impact and abrasion | |
Sea Stacks | Pillars of rocks rising above the water | |
Sea Caves | Hollow areas in rock created by by waves | |
Sea Arch | Forms when waves erode a layer of soft rock is under a layer of harder rock | |
Sea Cliff | Formed when waves erode and under cut rock to produce steep slopes | |
Beach | An area of wave washed sediment (sand, crushed shells and crushed coral) along a coast | |
Marsh | Wetland found at the end of a lake or stream | |
Barrier Island | A long, narrow island that forms along a coast. They protect the coast bay absorbing the energy of waves and storms | |
Sand Dunes | Are both formed and moved by water | |
Loess | Very fertile sediments of quartz, feldspar hornblende, mica,and are deposited by wind | |
Groundwater | The water located within the rocks below the Earth's surface | |
Mass Movements | A movement of a section of land down a slope |
