Erosion
Stack #221175
| Question | Answer |
|---|---|
| Cavern | area in bedrock that groundwater has dissolved |
| Sinkhole | formed when a cavern collapses |
| Creep | very slow movement of soil down slope |
| Groundwater | water in the ground |
| Slump | a section of soil moves in one unit down slope |
| Landslide | sediments slide down slope individually |
| Wave arch | arch in a rock formed by waves that wrap around the rock and bang into the side eroding the rock to form an arch |
| Stack | a pillar left over after the rock with an arch has almost completely eroded |
| Cliff | formed by waves undercutting rock |
| Wind arch | formed when wind “sand blasts” the less resistant or weaker exposed bedrock |
| Terrace | flat eroded rock worn down by waves |
| Sediment | particles of weathered rocks |
| Stream | moving water |
| Stream bed | bottom of stream |
| Meander | wide curve of a stream |
| Delta | sediments deposited by a stream at the mouth of a body of water |
| V-shaped valley | valley formed by streams |
| Downcutting | streams cause erosion by cutting through rock and soil |
| Stream bank | side of stream |
| Floodplain | formed by stream deposition when stream floods it deposits sediments on the side of stream |
| Fertile soil | formed by years of depositions of sorted sediments |
| Deposition | when sediments are deposited |
