Water

Water is found in rivers, lakes, oceans, seas, etc. These are called water bodies. More than two third of the earth is covered with water. Most of the water on the earth is salt water. We need fresh water to drink, which is only a very little portion of all the available water on earth.

A major portion of fresh water available in the form of glacier ice, at the north and south poles. It is far away from us. Therefore, we cannot use it.

 

Uses of water

  • Drinking
  • Washing

  • In industry and for many other purposes.

 

Air

Air is all around us. We cannot see it. But we can feel it. Moving air is called wind. A gentle wind is called breeze. When wind blows very fast, it is called storm.

Air is very necessary for all of us to live. We take in air when we breathe. But the air we breathe must be clean and fresh. Unclean air makes us sick. We get fresh air from trees and plants.

 

Weather

Our earth is surrounded by air. Sometimes this air becomes cold, sometimes hot. Sometimes we have rain, sometimes it is neither too hot nor too cold. This condition of a place, at any given time, is called weather.
