Summary - The basis of life on earth is atmospheric cover on earth and natural cycles like carbon, oxygen, nitrogen and hydrological cycles. Atmosphere is evolved in its present form due to sunlight and rotation of earth on its axis. Many environmental changes like change in rainfall patt..

The atmosphere resource of our world is unique and available to our planet only. No other planet is found to have similar atmosphere. Earth's atmosphere is a legacy from history of this planet. It was formed billions of years back. In the formative years, as the earth started cooling, it did ..

The addition of certain pollutants like the carbon dioxide gases increases the temperature of the earth. These gases remain close to the surface of earth, forming an insulating layer. The surface becomes hot due to the solar radiation..

The addition of certain pollutants like the carbon dioxide gases increases the temperature of the earth. These gases remain close to the surface of earth, forming an insulating layer. The surface becomes hot due to the solar radiations. This radiation is normally reflected back into the s..

Most of the solar radiation entering the earth's atmosphere is reflected back into the space. However some of the heat is absorbed by the gases like the carbon dioxide. This serves to keep the earth warm much like the greenhouses. Greenhouses are glasshouses which maintain a temperature higher tha..

The natural 'Green-house Effect' is essential for life on earth. Various gases in the atmosphere like water vapour and carbon dioxide trap some of the outgoing radiation from the earth, retain the heat and keep the earth's temperature at levels where living things, including man, can survive. How..

Introduction - The term environment refers to the natural elements that make up the Earth and surround living organisms, enabling life. The study of the environment and its proper conservation, has gained enormous importance in last three decades. The term environmental pollution..

Realising the changes in global climate and human interferences resulting in such changes, many global conferences are held in order to reach consensus among countries to plan and implement the measures to mitigate the harmful effects of climate change. They were 1) Stock Holm ..

The substances/species produced either by a natural source or by human activity, which cause an adverse effect on the environment on being in excess of a desirable limit, are termed as pollutants. Some common examples of pollutants are carbon monoxide, sulphur dioxide, oxides of..
