उत्तर
Air is present everywhere but not in soil.
Explanation:
Air is omnipresent and is present in soil too. This can be inferred by adding water to a pot filled with a lump of soil. After adding water it can be observed that the soil absorbs all the water and air bubbles are formed. These air bubbles show the escaping air.
