Mass Movement/Water Erosion/Glaciers/Waves/Wind
Question | Answer |
---|---|
What is mass movement and what causes it? | Any process that moves sediment downhill |
What are the four types of mass movement? | Landslide,Mudslide, Creep, Slump. |
What is a Landslide? | Rock falling down a slope. |
What is a Mudslide? | Water and rock falling down a slope. |
What is a Creep? | Slow downhill movement of sediment |
What is a Slump? | Large rock all of a sudden goes downhill. |
What is the material moved by erosion? | Sediment |
What is deposition? | Creates deltas and alluvial fans, adds soil to rivers. |
What land features are created by erosion? | Waterfalls, Flood plains, Meanders, Oxbow Lakes. |
What is a waterfall? | When water flows over rock and falls to the ground. |
What is a meander? | Widining, zig zagging course through a river |
What is an oxbow lake? | piece of a river that's no longer being flowned into. |
What is a flood plain? | A plain formed by sediment |
What features are made by deposits from rivers? | Alluvial Fans and deltas. |
What are alluvial fans? | when a stream leaves a mountain range shaped like a fan. |
What is a delta? | Sediment deposited where river flows into a lake or an ocean. |
What is Karst Topography? | Weathering caused by groundwater erosion |
What two features can form from groundwater deposition? | Stalactite, stalagmite |
What is stalactite? | on roof, like an icicle |
What is stalagmite? | Cone shaped and on the floor. |
What features can form from groundwater erosion? | Caves and caverns |
What's Till? | A mixture of sediments that the glacier deposits |
What are the land features that can be made by glacial erosion? | arete, horns, cirques, and glacial lakes. |
What is moraine? | Till deposited at the edge of a glacier. |
What is Drumlin? | Long mound of till, shaped in the direction of glacier flow |
What are kettle lakes? | small depression, forms when chunk of ice is left in glacier till |
What land features are made from wave erosion? | Sea caves, sea arches, sea stacks, and wave cut cliffs. |
What is a spit? | sediment carried on beach by a long shore current. |
What is runoff? | Water that flows over the ground surface rather than soaking into the ground. |
What are the five factors that control the amount of runoff? | Rain, vegetation, soil, land shape, and how people use land. |
What are rills? | Tiny grooves in soil |
What is a gully? | Large groove or channel in the soil that carries runoff after a rainstorm. |
What is a stream? | A channel along which the water is continually flowing down a slope. |
What is a river? | A large stream |
