Water - Erosion
Vocabulary review of water erosion and deposition
| Question | Answer |
|---|---|
| soaks into ground | groundwater |
| surface water erosion from runoff that makes small channels | rill erosion |
| rain and sediments running over a gentle slope | sheet erosion |
| a bend or curve in a river | meander |
| water quickly loses energy and deposits sediments in a triangular shape | alluvial fan |
| a river emptying into a ocean forms this triangular deposit | delta |
| soil or water through which water can move | permeable |
| a large mass of permeable rock that water can easily move through | aquifer |
| all pores in the rock are filled with water in this area | zone of saturation |
| the surface just above the zone of saturation | water table |
| type of topography where carbonate rocks form caves, sinkholes and underground streams | karst |
| made of deposits of sand and other sediments and runs parallel to the shore | beach |
| limestone dissolves and forms this underground feature | cave |
| underground rocks heat groundwater which comes out onto Earth's surface | hot spring |
| a type of well that brings water to the surface by natural pressure | artesian well |
| water that reaches streams, etc. by flowing on top of Earth's surface | runoff |
| surface water erosion caused by fast moving water making huge channels in rock or soil | gully erosion |
| a watershed or large land area that is drained by rivers that form a system | drainage basin |
| flat land that is flooded when a river overflows during a flood | flood plain |
| soil or rock that water cannot easily move through | impermeable |
| a water source where the water table is at the Earth's surface | spring |
| an erupting hot spring | geyser |
| this ocean current runs parallel to the shoreline | longshore current |
| a long, narrow island made of sand that is parallel to the shore | barrier island |
