Mass Movement, water, wind, waves, glaciers
| Question | Answer |
|---|---|
| What is mass movement and what causes it? | Mass movement is when land moves downhill. Gravity |
| What is the material moved by erosion called? | sediment |
| What is deposition? | when the agents of erosion lay down sediment. |
| tiny grooves in the soil | Rills |
| a large groove in the soil that carries runoff after it rains | Gullys |
| a channel where water is continually flowing downhill | Stream |
| a large stream | River |
| landscape that has a lot of caves and sinkholes | Karst Topagraphy |
| a calcite deposit that hangs from the ceiling of the cave | stalactite |
| calcite, is the shape of a cone, and builds up of the cave floor | stalagmite |
| the sediment deposited directly by a glacier | Till |
| mounds or ridges of till | Moraine |
| long mound of till smoothed in the direction of a glacier | Drumlin |
| a small depression that is formed when a block of ice melts in till | |
| pile of sand above sea level. It protects the main land from storm surge | Barrier Beach |
| a long ridge of sand parallel to the shore. It is formed when incoming waves carrying sand deposit the sand | Sandbar |
| a beach that projects into the water like a finger. It is formed from deposition of a longshore drift | Spit |
| What is the difference between a sand dune and a loess? | The difference between sand dunes and a loess is that a sand dune is made up of courser sediment and a loess is finer sediment. Also, sand dunes can be larger and loess can be fertile for plating |
| What is runoff? | water that moves over Earth’s surface |
| What are the four types of mass movement | landslide, mudslide, creep, slump |
| when rock and soil slide down a steep slope | landslide |
| when a mixture of water, rock, and soil, slide downhill | mudslide |
| when a mass of rock and soil slip down a slope in one large mass | slump |
| when soil and rock go downhill very slowly. It happens very slow and tilts objects at angles | creep |
| What features are made by deposits from rivers | deltas and alluvial fans |
| The process where wind picks up sediment and puts it down is called . | |
| What force causes a wave to slow down and break when it reaches shallow water? | friction |
| What land features are made from wave erosion? | wave cut cliff, sea stack, sea arch, sea caves |
| when waves erode a hollow area in the rock | A sea cave |
| when the base of the rock is eroded and the rock above it collapses | |
| when waves erode a hole through the softer rock that is under the harder rock | sea arch |
| when the arch collapses and leaves a pillar of rock | sea stack |
| How do waves form? | |
| when wind removes surface materials | deflation |
| when currents parallel to the beach make sediment move down the beach | long shore drift |
| weakest agent of erosion | wind |
| only effective in deserts | wind |
| erodes by impact and abrasion | waves |
| when glaciers pick up rocks | plucking |
| The time where continental glaciers cover much of the Earth | ice age |
| fine, wind deposited sediment | leoss |
| a pile of sand that is formed because wind has struck an obstacle | sand dune |
| a glacier that is formed on a mountain and goes in one direction | |
| glaciers that are on land, very large, and go in all directions | continental glacier |
| a large mass of ice that moves slowly over land | glacier |
| a smaller stream that flows into a larger river | |
| a land area where a river and its tributary's collect water | drainage basin |
| high ground between drainage basins | divide |
| Divide that runs through the rocky mountains | continental divide |
| large groove or channel that carries runoff after it rains | gully |
