GEOLOGY

Detailed explanation-1: -Mountains grow at a relatively fast rate (a few mm/year) until the forces that formed them are no longer active. Even while they are growing, they are being cut down by the processes of erosion. These processes include wind blown sand eating away at surfaces, ice in glaciers scouring the surfaces, and water in streams.

Detailed explanation-2: -Sediment moves from one place to another through the process of erosion. Erosion is the removal and transportation of rock or soil. Erosion can move sediment through water, ice, or wind. Water can wash sediment, such as gravel or pebbles, down from a creek, into a river, and eventually to that river’s delta.

Detailed explanation-3: -In temperate regions the rate of erosion is proportional to the average steepness of the topography, apparently because gravity-and water-driven processes are more effective on steeper slopes.

Detailed explanation-4: -Erosion is a natural process that can have significant effects on mountains. It is the wearing away of the surface of the earth, often caused by the action of water, wind, and ice. Over time, erosion can cause mountains to become lower and less steep, and can even lead to the complete erosion of a mountain.
