76) What is the major role of a greenhouse gas that contributes to temperature rise of the Earth's surface?
Explanation:
Solar energy heats the earth’s surface. But the energy does not stay bound up in the earth’s environment forever. Instead, as the earth warms, it emits thermal radiation. This thermal radiation, which is largely in the form of long-wave infrared rays, eventually finds its way out into space, leaving the earth and allowing it to cool. However, not all of the infrared rays pass into space. Some of the infrared rays are absorbed by greenhouse gases and warm the atmosphere. So the amount of greenhouse gases in the atmosphere is directly related to the temperature of the atmosphere.
