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 su..

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 ..

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 tempera..

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 pattern, rise ..

Introduction - 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..

Greenhouse effect accounts for 75% of global warming, and of this, CFC's contribute 15%. What percent of greenhouse effect is due to CFC's? => 42% or 8% or 30% or 20%..

The dipole pattern of earth's magnetic field is disturbed due to solar winds. Solar winds are a stream of charged particles coming from the sun. These particles ionise the atmosphere above these poles which display a light high up in the atmosphere. This phenomenon occurring in the arctic region is..

Increase in air temperature - popularly called as global warming - refers to mean temperature of entire globe averaged over all months and all places. Hence, the change in temperature at a place, in a particular month, may or may not match closely ..

The temperature of a room is 65° F. Is it hot, cold, or warm? => hot or cold or warm or I don′t know...
