Question

What is the Greenhouse effect?

Answer 1

The green house effect is the phenomenon in which infrared radiations of long wavelength given out from the surface of a planet are absorbed by its atmospheric gases to keep the environment at the planet's surface and the lower atmosphere warm.
The green house gases present in the earth's atmosphere play a role similar to that of glass walls of a green house. Hence this phenomenon is called the green house effect.
The increase in the concentration of carbon dioxide due to above human activities is responsible for 60% increase in green house effect
