Q6
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
AnswerD.
Absorption and re-emission of visible light by clouds
E.
Absorption and re-emission of visible light by the ground
Answer: Option C
Solution
Answer: Option C
Solution:
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.
