|---|---|
| erosion caused by the sandblasting effect of windblown sediments is called | abrasion |
| is the triangular fan shaped deposit of sediment that forms where a river empties into an ocean or lake | delta |
| forms when river waters empty from a mountain valley out onto a flat open plain | alluvial fan |
| determines the amount of runoff | all- the amount of vegetation, the amount of rain and the slope of the land |
| a stream that flows swiftly through a steep valley and has steep sides is a ____ stream | young |
| forces that act on coastlines cause them to | change constantly |
| the major force behind mass wasting is | gravity |
| are ridges of till left behind when a glacier stops moving forward | maranes |
| is erosion that happens as gravity moves materials downslope | mass wasting |
| today continental ice sheets only exist in | Antarctica and Greenland |
| the mixture of different sized sediment that is deposited when a glacier retreats | till |
| an alluvial fan is a fan shaped deposit of sediments that forms when ___ loses its energy of motion | water |
| is formed when water empties into a lake or ocean | delta |
| windblown deposits of silt and clay | loess |
| sediment deposited by streams that flow from a melting glacier | outwash |
| the laying down or settling of eroded material | deposition |
| a process that wears away surface materials and moves them from one place to another | erosion |
| a jumble of materials deposited by a retreating glacier | till |
| the grinding away of rocks or other surfaces by windblown particles | abrasion |
| the broad, flat area located next to a river | floodplain |
| formed when sediments are deposited as water empties into an ocean or lake | delta |
| a current that flows parallel to the shoreline | longshore currents |
| deposit formed when river waters empty out onto a flat open plain | alluvial fan |
