With reference to the Earth’s atmosphere, which one of the following statements is correct?

(a)

The total amount of insolation received at the equator is roughly about 10 times of that received at the poles.

(b)

Infrared rays constitute roughly two-thirds of insolation.

(c)

Infrared waves are largely absorbed by water vapour that is concentrated in the lower atmosphere.

(d)

Infrared waves are a part of visible spectrum of electromagnetic waves of solar radiation

Answer:

(c)

Core Books/NCERT

Explanation

The correct answer is (c). The atmosphere is largely transparent to short wave solar radiation. The incoming solar radiation passes through the atmosphere before striking the earth’s surface. Within the troposphere water vapour, ozone and other gases absorb much of the near infrared radiation. This is given in NCERT Class12 Geography.
