Answer 2

Answer:

Sieving is a process by which fine particles are separated from bigger particles by using a sieve. It is used in flour mill or at construction sites. In flour mill, impurities like husks and stones are removed from wheat. Pebbles and stones are removed from sand by sieving.

Winnowing is used to separate heavier components from the lighter components by blowing air. It is used to separate lighter husk from heavier grains of wheat and rice.
