Environmental Pollution

Objectives
Man is one of the species who inhabit the earth.he is the only one who has interfered with various natural processes for use of both biological & physical resources to meet his multiple demands,man has polluted all the three realms of the earth-lithosphere,hydrosphere & atmosphere.it is essential for us to know about environment & its pollution.
In this presentation we will be able to know about-

•Environment
•Biosphere
•Ecosystem model
•Atmosphere
•Atmospheric pollution •Primary & secondary pollutants •Acid rain
•Ozone depletion
•Green house effect
•Noise pollution

That which surrounds, the total sum of the condition of the surroundings within which an organism, or group, or an object,exists(including the natural as modified by human activity & the artificial).

Soil

Sun provides energy for plant photosynthesis Amount of solar radiation varies with latitude & hence effects climate. solar radiation also power weather systems
Volcanic activity ,mountain, ranges etc. can also affect climate
Climate interacts with geology in soil formation provides water for solar climate. Soil provides water & nutrients for plants together with a physical base in which plants can root themselves.

Plants provides food for animals Animals alter vegetation by browsing & grazing. Human have significantly altered vegetation patterns through modification for agriculture. Vegetation gives off water vapour who helps to stabilize the climate of the earth. Climate restricts the type of plants & animals that can survive in a particular ecosystem. Water &
