Question

Gradation with reference to "wind".

Answer 1

Answer:

Explanation:

• The wind can be regarded as the active agent for gradation generally in desert. It blows due to less vegetation.
• The dust and sand particles can be carried over the greater distance. The particles get deposited when wind velocity decreases or when an obstruction is there in path of wind.
• Wind performs transportation, erosion and deposition as the agents of the gradation and created various features.

Answer 2

Gradation with reference to wind:

Wind is an air stream moving from one place to another. Air on the ground surface continuously moves from areas of high pressure to areas of low pressure. This movement transmits the dust and sand particles with it. These particles are transported hundreds of kilometers away and are deposited there. The major features made by wind are mushroom rocks, sand dunes and loess.

EXPLANATION:

Wind is an active agent of gradation mainly in deserts. It blows unrestrained owing to lack of vegetation. The dust and sand particles are transported over greater distance. Wind is an air stream moving from one place to another. Air on the ground surface continuously moves from areas of high pressure to areas of low pressure.

This movement transmits the dust and sand particles with it. These particles are deposited when the wind velocity decreases or when there is an impediment in the wind’s path.

Wind does transportation, deposition and erosion, similar to other gradation agents such as waves, rivers, etc. and forms features such as mushroom rock, sand dunes, and loess.
