The glass panels of the greenhouse let in light but keep heat from escaping.
This causes the greenhouse to heat up.</li></li></ul><li>Green house gases<br />Any gas that absorbs infra-red radiation in the atmosphere.<br />water vapour<br />Nitrous oxide (N2O)<br />C<br />O<br />O<br />C<br />O<br />O<br />Halogenated Chlorofluoro carbons (HCFCs) <br />Carbon dioxide (CO2)<br />methane (CH4)<br />Ozone (O3)<br />Hydrofluorocarbons (HFCs).<br />
Green house effect<br />Carbondioxide present in the atmosphere absorbs infrared radiations reflected from the surface of the earth and heats up the atmosphere.<br />This heating up of atmosphere by carbondioxide in the air is called green house effect.<br />
Greenhouse gases in the atmosphere behave much like the glass panes in a greenhouse.<br />
Importance of the greenhouse effect<br />Without the greenhouse effect, the Earth would not be warm enough for humans to live.<br />But if the greenhouse effect becomes stronger, it could make the Earth warmer than usual. <br />
Global warming<br />Because of Green house effect the average temperature of the earth increases and this is known as Global warming<br />
Sunlight enters the Earth's atmosphere, passing through the blanket of greenhouse gases.<br />
Sunlight’s energy emains trapped in the atmosphere<br />
