Water Erosion and Deposition Chapt. 9 vocab
| Question | Answer |
|---|---|
| water that doesn't soak into the ground or evaporate but instead flows across Earth's surface | runoff |
| groove created by water moving down the same path | channel |
| occurs when water that is flowing as sheets picks up and carries away sediments | sheet erosion |
| is the area of land from which a stream or river collects runoff | drainage basin |
| broad, c-shaped curve in a river or stream, formed by erosion of its outer bank | meander |
| water that soaks into the ground and collects in pores and empty spaces and is an important source of drinking water | groundwater |
| describes soil and rock with connecting pores through which water can flow | permeable |
| describes materials that water cannot pass through | impermeable |
| a layer of permeable rock that lets water move freely | aquifer |
| upper surface of the zone of saturation; drops during a drought | water table |
| forms when the water table meets Earth's surface; often found on hillsides and used as a fresh-water source | spring |
| is a hot spring that erupts periodically, shooting water and steam into the air | geyser |
| underground opening that can form when acidic groundwater dissolves limestone | cave |
| current that runs parallel to the shoreline, is caused by waves colliding with the shore at slight angles, and moves tons of of loose sediment | longshore current |
| deposit of sediment whose materials vary in size, color, and composition and is most commonly found on a smooth, gently sloped shoreline | beaches |
