Mass Movement , Glaciers , and Erosion Study Guide
| Question | Answer |
|---|---|
| A _______ is any large mass of ice that moves slowly of land? | Glacier |
| Times when continental glaciers cover large parts of earths surface are called _________. | Ice Ages |
| A glacier picks up rocks through a process called ___________ . | Plucking |
| The sediment deposited directly by a glacier is called _____________. | Tills |
| A Moraine is __________________________ | Mounds or ridges of till deposited at the end of a glacier |
| A Horn is ____________________________ | A sharpened peak |
| A Cirque is ______________ | A Bowl-shaped hollow |
| A Kettle Lake is __________________ | |
| What is the most important type of erosion? | Water Erosion |
| When waves crash onto the beach at an angle a _________ is created along the coastline. | Longshore drift |
| The process where wind picks up sediment and moves it is called _______ | Deflation |
| What is till? | A till is the sediments that are deposited directly by a glacier j |
| A Drumlins is _______________ | A large mound of till that is higher on one end |
| OWhat land features are made from wave erosion? | Sea Arches , Sea Stacks , Sea Caves , Wave Cut Cliffs |
| What is a Barrier beach? | A barrier beach forms when storm waves pile up sand above sea level. |
| What s a sandbar? | A sand bar is large ridges of sand parallel to shore n |
| What is a spit? | A beach tah projects like a finger out into the water. Headland interrupts a longshore drift. |
| What is mass movement and what causes it? | Mass Movement is Mass movement are several proceses that move downhill, caused by gravity. |
| What are the four types of mass movement? Explain each type. | The Four types of Mass movement are slump , creep , mudslide , and landslide. A mudslide is the rapid downhill movement of a mixture of water, rock and soil. A creep is a very slow downhill of rock and soil. |
| What are the four types of mass movement? Explain each type. ( Continue ) | A landslide is the most destructive type of mass movement, which happens when rock and soil quickly slide down a steep slope. A slump is when a mass of rock and soil suddenly slips down a slope. |
| What is the material moved by erosion called? | The Material moved by erosion is called sediment |
| What is deposition? | Deposition is the change of land. Deposition occurs where the agents of erosion lay down sediment. |
| What is the major agent that has shaped Earth’s surface? The | The major agent that has shaped Earths surface is Moving Water. Moving Water creates Landforms |
| What is runoff? List and explain the five factors that control the amount of runoff. | A run off is all the remaining water that moves over earth’s surface Define |
| Rills | Tiny grooves in the soil, as runoff travels. |
| Gullys | A large groove, or channel, in the soil that carries runoff after a rainstorm. |
| Stream | A channel along which water is continually flowing down a slope. |
| RIver | A large Stream |
| What land features are created by water erosion? Explain each one. | The land features created by water erosion are valleys, waterfalls, flood plains, meanders, and oxbow lakes. Oxbow lakes are when meanders are cut off. A landslide is a flat, wide area of land along a river. |
| What land features are created by water erosion? Explain each one. ( continue ) | A meander is a looplike bend in the course of a river. Waterfalls occur when a river meets an area of rock that is very hard to weather away and there is softer rock farther down the river. |
| What features are made by deposits from rivers? Explain each one. | The land features created by deposition are alluvial fans , and deltas. It creates alluvial fans when a stream flows out of a steep mountain valley , as it becomes wider and shallower. |
| What features are made by deposits from rivers? Explain each one. ( continue ) | An alluvial fan is a wide , sloping deposit formed where a stream leaves a mountain range . A delta is sediment deposited where a river flows into a ocean or lake builds up landform. |
| What is Karst Topography | Karst Topography is Landsacpe marked by caves and sinholes |
| What is stalagmite? | calcite deposit from floor of a cave |
| What is stalactite? | calcite deposit form the ceiling of a cave |
| What two features can form from groundwater deposition? | Caves and sinkholes |
