Question

The soil which is transported by wind is known as
A) Colluvial soil
B) Alluvial soil
C) Aeolian soil
D) Glacial soil

Answer 1

Hint: The provided options are on the basis of means of deposition of the soil. (that means that the name is given after the depositing agent of the soil).

Complete solution:
Let us evaluate all the four options:
A) The first option is Colluvial soil. It is that type of soil which gets deposited down due to the gravitational force. They are typically coarse grained and immature, deposited in the lower part and foot zone of a mountain, slope or other topographic escarpment, and they are brought there chiefly by sediment-gravity processes.
B) The next option is alluvial soil. It is the type of soil which is strongly transported by running water. These generally get deposited at the river banks. Alluvial soil consists of silt, sand, clay, and gravel and often contains a good deal of organic matter, and that is why it yields very fertile soil.
C) Now look at option D which is glacial soil. The type of soil which is transported by a Glacier is known as glacial soil.
D) The option left with us is options C Aeolian soil. This soil is transported by wind. Eolian (or Aeolian) sediments are wind deposited materials that consist primarily of sand or silt-sized particles. These materials tend to be extremely well sorted and free of coarse fragments. Some rounding and frosting of mineral grains is detectable.
The perfect example of this type of soil are sand dunes which often get deposited in the sandy areas like that of Rajasthan.

so, the correct answer is option C.

Note:
The soil transported by wind is known as Aeolian soil. You can well relate Aeolian soil with sand dunes.
