WATER EROSION AND DEPOSTION

Runoff


 Water that doesn't soak into the ground or evaporates but instead flows across Earth's surface is called runoff.

Channel

 Groove created by water moving down the same path.

Sheet Erosion

a type of surface water erosion caused by runoff that occurs when water flowing as sheets picks up sediments and carries them away. 

Drainage Basin
land area from which a river or stream collects runoff.

Meander

broad, c-shaped curve in a river or stream, formed by erosion of its outer bank

Groundwater

water that soaks into the ground and collects in pores and empty spaces; important source of water.

Permeable

describes soil and rock with connecting pores through which water can flow. 

impermeable  

describes materials that water cannot pass through. 

aquifer

 layer of permeable rock that allows water to flow though. 

water table

upper surface of the zone of saturation; drops during a drought. 

spring 

forms when water table meets Earth's surface; often found on hillsides and used as a freshwater source. 

geyser

hot spring taht erupts periodically and shoots water and steam into the air. 

cave

underground opening that can form when acidic groundwater dissolves limestone.

longshore current 

current that runs parallel to the shoreline, is caused by waves colliding with the store at slight angles, and moves tons of loose sediment.

beach

 deposit of sediment whose materials vary in size, color, and composition and is most commonly found on a smooth, gently sloped shoreline.
