Question | Answer |
Describe how gravity can act as an agent of erosion to move rock sediment. GIVE EXAMPLES | Landslides, Rockfall, Mudflows, Slump, Creep, Mass Material |
Landslides | the downward movement of rock, soil, mud, or various combinatons of materials |
Rock fall | occurs when sediment of any size drops from a cliff. |
Mudflows | a water saturated mixture of rock debris and soil moving down a slope |
Slump | the down slope movement of a intact mass of rock and soil |
Creep | the slow movement of soil and rock down a slope |
Mass Material | earth material transported down a slope by gravity |
Describe how weathering and erosion work together to cause formations in mountains deserts shorelines and rivers | |
How are Mountains formed | Receding glaciers can scrape carve and shape the land leaving behind pyramidal mountain peaks U-shaped valleys moraines and drumlins. Ice wedging water wind and gravity can further weather rocks forming steep mountain faces and causing mass movement. |
How are desert formations like fins, hoodoos,mesas, and buttes formed? | Weathering and erosion caused by sand, wind and water can sculpt and polish desert formations like ---- |
How are Sea cliffs and Islands weathered? | With wind and waves |
How are beaches formed? | Seacliffs and islands are weathered away resulting in some of the sand that accumulates on ---- |
How are peninsulas, isthmuses and coves formed? | by accumulation of sand |
How are deltas, and Sandbars formed? | Rivers deposit sediment and it builds up to create a ------ |
