Work of Wind
The wind is the active form of erosion and deposition in deserts. In deserts, rocks in the shape of mushrooms are seen, known as mushroom rocks. Winds erode the upper portion more than the lower portion, and hence bottom is narrow and wider at the top. When the wind stops blowing, the sand falls and gets deposited in low hill structures known as sand dunes. When such sands are deposited in large amounts, it is called loess.
Major Landforms of the Earth
Major Landforms of the Earth: Landforms refer to the physical features that are present on the surface of the Earth. It includes mountains, plateaus, and plains. Natural processes which include the weathering, water, sinking, elevation, and erosion of soil lead to the constant re-shaping of the surface of the earth and take thousands of years to formulate. Landforms are originated from geological processes:
External Process
External processes include external factors like rain or wind and it causes both erosion and deposition. Erosion refers to the processes in sediments that get deposited or dropped off in different areas.
Internal Process
Internal process refers to those processes that occur within the surface of the earth and examples include volcanic eruptions and also the movement of tectonic plates.
