Water and Erosion
| Question | Answer |
|---|---|
| Mechanical/ Chemical | types of erosion |
| wind, water, ice, chemicals | major forces of erosion |
| water | the most powerful force of erosion in nature |
| weathering | the breaking down or disintegration of substances such as rocks and minerals by physical or chemical or processes |
| erosion | the movement of sediment or soil from one location to another by means of water, ice, or wind |
| deposition | when particles carried by water, ice, or wind are deposited in another location |
| mass wasting | the general term for the movement of large masses of rocks and soil caused by GRAVITY (fast or slow) |
| stream erosion | weathering or erosion due to running water |
| terracing | cutting level areas into a slope to slow the process of erosion |
| landslide | the SUDDEN movement of large amounts of dirt and rock |
| avalanche | the SUDDEN movement of large amounts of ice and snow |
| creep | form of mass wasting with the SLOW movement of dirt and rocks |
| lava tubes | caverns formed as the outer layers of lava cooled (after a volcanic eruption) |
| solution caves | cavern formed erosion due to underground water (this is the most common type of cave) |
| sea caves | caverns formed by erosion due to the pounding of waves |
| sandstone caves | caves formed at the base of cliffs by moving water |
| stalactites | calcite formation in a cave hanging from the ceiling |
| stalagmites | calcite formation on the floor of a cave (coming up from the floor) |
| column | a structure formed when stalactites and stalagmites grow together |
| flowstone | thin layer of minerals covering the surface of a cave |
| curtain | flowstone that hangs from the ceiling of a cave |
| humus | decayed plant matter that makes up a portion of soil and must be present in order for plants to grow |
| permeability | the rate at which water flows through soil |
