What is Air?
Air is a mixture of different gases in the atmosphere.
No living things can survive without air. We can live without food and water for few days but we can’t live without air for more than a few minutes.
Where is Air present?
- Air is present everywhere (even though it cannot be seen by us), it is present in the atmosphere, water and soil.
- Things which seem to be empty are also filled by Air.
- Although we cannot see air, its presence can be felt in a lot of different ways like rustling of leaves, fluttering of pages when the fan is turned on etc.
What is Wind ?
Air in motion is called Wind.
In easy language, when air moves from one place to another it is known as Wind.
