Solution:
The process used to separate heavier components of a mixture by wind is called winnowing.To remove the husk from seeds and grains, farmers use a process known as winnowing. In this process, heavier and lighter components of a mixture are separated by the help of wind or blowing air. Chaff is also removed from grains using this process. In this process, grains are allowed to fall from a certain height. Since the husk is lighter than the grains, it is removed efficiently by air blow.
