The atmospheric greenhouse effect is produced mainly by the:
A. Absorption and re-emission of visible light by the atmosphere
B. Absorption and re-emission of ultraviolet radiation by the atmosphere
C. Absorption and re-emission of infrared radiation by the atmosphere
D. Absorption and re-emission of visible light by clouds
E. Absorption and re-emission of visible light by the ground
Answer: Option C
Solution(By Examveda Team)
The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without this atmosphere.Radiatively active gases (i.e., greenhouse gases) in a planet's atmosphere radiate energy in all directions. Part of this radiation is directed towards the surface, warming it. [3] The intensity of the downward radiation – that is, the strength of the greenhouse effect – will depend on the atmosphere's temperature and on the amount of greenhouse gases that the atmosphere contains.

D. A way of distinguishing between "new" and "old" clouds.
The greenhouse effect is primarily a function of the concentration of water vapor, CO2, and other trace gases in the atmosphere that absorb the terrestrial radiation leaving the surface of the Earth, and act like a blanket over the earth's surface, keeping it warmer than it would otherwise be….
