Life on Earth it impossible because of air and water. We use Air in respiration. Air contents of oxygen which is a life sustaining gas. Similarly we drink water. It helps in digestion of food. It also contains oxygen which is essential for our body.
Not only do we use water for drinking purpose but we also use it for various other purposes. We use water to cook our food. We use water for cooking rice and for making curry.
Water in a purified form is used for making medicines. Cold drinks that we use on a large scale are made with water. Different kinds of Squash are also made with water.
In a cylinder a mixture of air and water is imprisoned. It is then made air tight. When we bang it ,it explodes and steam comes out with great force. The force runs the engine of a railway carriage or a ship.
Electricity that we need very much in life is also generated from water.
Water in rivers ,Ponds and seas is evaporated in hot summer and it comes down in rain letter in the rainy season and in the other season also. Rain is very much necessary for crops that sustain our life.
So we need water for various purposes.
