Impacts on Air

Impacts on Water

Impacts on Land

In this unit, we will have an overview of the various natural and artificial

impacts on air, water, land. Before we proceed you have to understand that

impacts are created by both nature and man. But the impacts of man are more

pronounced. In this unit, we shall only mention the various impacts which the

student may be already aware. A detailed study of these impacts is the scope of

the topic “Stress on physics, chemistry and biology of water owing to impacts”.

Therefore in this chapter, the impacts of nature and man on air, water and land

would be listed.
