Greenhouse gases absorb infrared radiation and trap it as _______.



Answer :

Earth's ozone layer is responsible for absorbing ultraviolet rays from the sun.

Changes in the composition of the atmosphere have caused gradual changes in the earth's temperature throughout history, causing changes in plant and animal life that contributed to mass extinctions.

Chemical chlorofluorocarbons (CFCs) have been banned and replaced with hydrofluorocarbons (HFCs), which destroy about 1 percent of the ozone that CFCs do.

Naturally occurring volcanic eruptions can produce large amounts of gases that contain sulfur. These gases accumulate in the atmosphere in the same way as man-made gases. Greenhouse gases absorb infrared radiation and trap it as warmth.
