Plain formed by Wind Deposition The two features that are formed by wind deposition are Sand dunes and loess deposits. The dunes are also called Aeolian Landforms. The wind is a good sorting agent. Based on the velocity of the wind, varying sizes of grains are moved along the floor by saltation, or by rolling, … Read more
The wind is one of the two dominant agents in hot deserts. The desert floors get heated up too much and too quickly because of are dry and barren. The heated floors heat up the air directly above them and result in upward movements in the hot lighter air with turbulence, and any obstructions in … Read more
Depositional landforms of sea waves Important depositional landforms of sea waves are sea beaches, bars, barriers, splits, offshore, etc. Beaches and Dunes Beaches Beaches are characteristic of shorelines that are dominated by deposition but may occur as patches along even the rugged shores. Most of the sediment making up the beaches comes from land carried … Read more
WAVES AND CURRENTS Coastal processes are the most dynamic and hence most destructive. Some of the changes along the coasts take place very fast. At one place, there can be erosion in one season and deposition in another. Most of the changes along the coasts are accomplished by waves. When waves break, the water is … Read more
Glacial depositional landforms Glacial depositional landforms are formed from the action of glaciers. Most of the Glacial depositional landforms are formed by the movement of large ice sheets. Most of the famous areas for such glacier landforms are Fennoscandia, Andes, etc. Formation The unsorted sediments, unassorted coarse and fine debris are dropped from the glacier … Read more
Cirque Cirques are the most common landforms in glaciated mountains. The cirques quite often are found at the heads of glacial valleys. The accumulated ice cuts these cirques while moving down the mountain tops. They are deep, long, and wide troughs or basins with very steep concave to vertically dropping high walls at its head … Read more
Transportation and Deposition of Rocks Erosion is a natural process by the top layer of soil, rock or material on the surface of earth is removed by transported to another location by means of water, wind etc. Weathering is an important process, which is part of erosion where is helps in break down of rock … Read more
The rocks debris is transferred down the slopes due to gravity. It also suggests that the debris is not influenced by Air, water, or Ice to move from place to place. But the debris moves the water, ice, and Air. The mass movements also called slope movement or mass wasting are both slow and fast … Read more
