| Question | Answer |
|---|---|
| What causes Mass Movement? | Gravity |
| What is Mass Movement? | When a mass of land moves |
| What are the four types of Mass Movement? | A Landslide, a Slump, a Mudflow, and a Creep |
| What is the material that is moved by erosion? | Sediment |
| What is a landslide? | When rock and soil quickly slide down a steep slope. |
| What is a Slump? | A mass of rock and soil that suddenly slips down a slope. |
| What is a Mudflow? | The rapid downhill movement of a mixture of water, rock, and soil. |
| What is a Creep? | The very slow downhill movement of rock and soil. |
| What is Deposition? | When the agents of erosion lay down sediment. |
| What is the major agent that has shaped Earth’s surface? | Moving Water |
| What is runoff? | All the remaining water that moves over Earths surface. |
| What are the 5 factors that control the amount of runoff? | 1.The amount of rain in an area. 2.Vegetation. 3.The type of soil. 4.The shape of the land. 5.How people use the land. |
| What are Rills? | Tiny grooves in the soil |
| What are Gullys? | A large groove in the soil that carries runoff after a rainstorm. |
| What is a Stream? | A channel in which water is continually flowing down a slope. |
| What is a River? | A large stream. |
| What land features are created by water erosion? | 1.Valleys 2.Waterfalls 3.Floodplains 4.Meanders 5.Oxbow Lakes |
| What is a Valley? | Steep slopes along the river. |
| What is a Waterfall? | When water falls off a rock that is too hard to erode. |
| What is a Floodplain? | The flat wide are of land along a river. |
| What is a Meander? | A looplike bend in the course if a river. |
| What is an Oxbow Lake? | A meander that has been cut off from the river. |
| What features are made by deposits from rivers? | 1.Alluvial Fans 2.Deltas 3.Soil on flood plains |
| What is an Alluvial Fan? | A wide sloping deposit of sediment formed where a stream leaves a mountian range. |
| What is Delta? | Sediment deposited where a river flows in to an ocean or lake builds up a landform. |
| What is soil on flood plains? | When rivers flood and they leave sediment on the flood plains. |
| What is Karst Topography | Karst Topography is when the roof of a cave colllapses because of the erosion of the underlying limestone. |
| What is till? | The mixture of sediments that a glacier deposits directly on the surface after it melts. |
| What is the process where wind picks up sediment and moves it? | Deflation |
| What are the land features that can be made by glacial erosion. | A Cirque, an Arête, a Horn, a V & U shaped Valleys, and a Fjord. |
| What is a Moraine? | The till deposited at the edges of a glacier that forms a ridge. |
| What is a Drumlin? | A long mound of till that is smoothed in the direction of the glaciers flow. |
| What is a Kettle Lake? | A depression left in till by melting ice fills with water. |
| What force causes a wave to slow down and break when it reaches shallow water? | Friction |
