Detailed Solution

The above statement is true.
Winnowing is used to separate a substance that is heavier than the other. This process separates the lighter component from the heavier component using wind or blowing air. For example, winnowing is used to separate husk or chaff from the grains with the help of wind or by blowing air. The grains are taken in the winnowing basket or winnow and are dropped from a higher platform. The lighter particles that are husk or chaff are blown away by the wind, and the grains fall, forming a heap. So this way, the husk is separated from the grains. The separated chaff is used as fodder for the cattle. Blowing wind plays an important role in the process of separation of grain from husk by winnowing.
