Wind winnowing is an agricultural method developed by ancient cultures for separating grain from chaff. It is also used to remove hay and chaff or other pests from stored grain. Threshing, the loosening of grain or seeds from the husks and straw, is the step in the chaff-removal process that comes before winnowing.
Answer:
You might have seen a farmer separating wheat grains from husk in a field. The farmer, standing on a high platform, simply allows the mixture of wheat and husk to fall down from a height. The wind has very little effect on the grains because they are heavy. So, it forms a heap vertically downward on the ground. The husk, being light is blown away from the wheat and forms a heap at a distance away from the heap of wheat. This process is known as winnowing.
