what is greenhouse effect?
Answers
Answer:
the trapping of the sun's warmth in a planet's lower atmosphere, due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet's surface.
Answer:
greenhouse effect is the increase in temperature on surface of earth due to concentration of greenhouse gases like Cfcs,methane, carbon dioxide water vapour
Explanation:
excess amount of gases like chlorofluorocarbons,methane, carbon dioxide,water vapour etc, from industries and various man's activities like vehicles ,coolants in refrigerator,ac's disturbs enenrgy balance and increases heat on earth . greenhouse gases in the atmosphere allow the near infrared rays from the sun to penetrate into the earth while the rest of the rays from the sun like visible light and infrared of short wavelength are reflected back from earth's surface.greenhouses gases do not allow heat radiated by heated earth to penetrate back into space.thus by preventing heat rays to escape into outer space,these gases add to the heat already available on the earth's surface.
