The light passes through the glass and creates heat in the house, but the heat isn't able to escape. Light (which creates heat) comes in, but heat can't leave, and so the greenhouse maintains a tropical environment.

Why is it important for us to have a greenhouse effect on earth?

The greenhouse effect is what keeps the heat in after the light energy is converted to heat energy. If we did not have a greenhouse effect, life would no longer exist since the entire earth would be below freezing.


Is nitrogen the most important gas in greenhouse gases?

No, carbon dioxide is the most important greenhouse gas, not nitrogen.


Are oxygen and nitrogen important greenhouse gases?

Independently, oxygen and nitrogen are not greenhouse gases (though N2O, NO and NO2 are greenhouse gases). The most important greenhouse gas is carbon dioxide. Methane, although found in quite low concentrations is also important because of its proportionately greater effect.


Does the greenhouse effect absorb sun light?

Yes It does.


Does earth radiating mostly infrared light cause the greenhouse effect?

Yes. The infrared radiation from the surface of the earth is captured by the greenhouse gases in the atmosphere. This causes the greenhouse effect.

Why is it important to be concerned about pollution and carbon dioxide?

It is important to worry about it, because carbon dioxide is a powerful greenhouse gas that is adding to the greenhouse effect in the atmosphere and contributing to global warming.


Identify one important effect of the rise in the level of greenhouse gases?

It is easy to identify one of the most important effects of the rise in the level of greenhouse gases and that is a rise in global warming.


Which gas can create the greenhouse effect?

Water vapour, carbon dioxide, methane and nitrous oxide are the most important greenhouse gases.


Removal of important forests such as these in brazil worzens the greenhouse effect why?

Forests absorb greenhouse gases. They are the ones that cause ozone depletion.


What happens as a result of the greenhouse effect?

We stay warm and survive. The greenhouse effect works like this. We get light energy from the sun. When that light energy hits the earth's surface, it turns into heat energy. The earth then heats up the atmosphere and the "greenhouse gases" hold this heat in keeping us warm. If not for the greenhouse effect, the earth's temperature would be about -160o C.


What happens to the size of the waves when reflected in the greenhouse effect?

Visible light radiation comes to us from the sun in the form of short wave ultraviolet light. This warms the surface of the earth. This warmth rises into the atmosphere in the form of infrared, long wave radiation, where it is captured by greenhouse gases in the greenhouse effect.
