Explanation:
Definition:
“Greenhouse effect is the process by which radiations from the sun are absorbed by the greenhouse gases and not reflected back into space. This insulates the surface of the earth and prevents it from freezing.”
Greenhouse Effect?
A greenhouse is a house made of glass that can be used to grow plants. The sun’s radiations warm the plants and the air inside the greenhouse. The heat trapped inside can’t escape out and warms the greenhouse which is essential for the growth of the plants. Same is the case in the earth’s atmosphere.
During the day the sun heats up the earth’s atmosphere. At night, when the earth cools down the heat is radiated back into the atmosphere. During this process, the heat is absorbed by the greenhouse gases in the earth’s atmosphere. This is what makes the surface of the earth warmer, that makes the survival of living beings on earth possible.
Greenhouse Gases
“Greenhouse gases are the gases that absorb the infrared radiations and create a greenhouse effect. For eg., carbondioxide and chlorofluorocarbons.”
Causes of Greenhouse Effect
The major causes of the greenhouse effect are:
Burning of Fossil Fuels
Deforestation
Farming
Industrial Waste and Landfills
List gases which are responsible for the greenhouse effect.
The major greenhouse gases are:
1) Carbon dioxide
2) Methane
3) Water
4) Nitrous oxide
5) Ozone
6) Chlorofluorocarbons (CFCs)
