Greenhouse effect science class ix kendriya vidyalaya
Answers
The greenhouse effect is the trapping of the sun's heat in the atmosphere of a planet by gases in that atmosphere. It's called the greenhouse effect because it has a lot in common with how the glass of a greenhouse traps heat inside: heat can get into the greenhouse but has more trouble leaving.
The greenhouse effect happens because of so-called greenhouse gases, which include carbon dioxide, methane, water vapour, and others. The biggest components of the atmosphere, nitrogen and oxygen, are not greenhouses gases.
Effect of Global warming
1)Increase in temperature can lead to melting of polar ice caps and ultimately rise in sea level for submerging a number of major cities in the world which are located along the sea coast.
2)Increase in temperature will result in changes in weather and precipitation pattern on earth.
The word green house comes from the house which was used early in cold countries for seed germination as in cold countries the amount of sunlight is not enough for seed germination.
Green house effect is the entering of solar radiation to pass in but prevent long wave heat radiation to pass out due to presence of solar gases. These gases allow the solar radiation to pass through but reflect back the long wave radiations back to earth , are called green house effect.
Carbon dioxide , chroro - floro carbon and nitrogen oxide are green house gases which are mostly produced by industries ,factories and by automobile's exhaust.
Due to green house effect the temperature of the surface of earth , on its immediate atmosphere rises and this phenomenon is called global warming.
Global warming leads to melting of glaciers , occurence of diseases , adverse effect on plant yields.
So we need to reduce the use of automobiles and we should stop deforestation and start afforestation.
Save green , Go green
