Q. Which of the following factors is/are responsible for the higher latitudes receiving less insolation?
Which of the statements given above is/are correct?
The correct option is D 2 and 3 only
Explanation:
Statement 1 is incorrect: The earth’s surface receives most of its energy in short wavelengths. The energy received by the earth is known as incoming solar radiation which, in short, is termed as insolation. The higher the latitude the less is the angle they make with the surface of the Earth resulting in a low angle of incidence.
Statement 2 is correct: The area covered by vertical rays is always less than the slant rays. If more area is covered, the energy gets distributed and the net energy received per unit area decreases. If the sun’s rays are oblique, the angle of incidence is small and the sun’s rays have to heat up a greater area, resulting in less amount of insolation received there.
Statement 3 is correct: The sun’s rays, with a small angle, traverse more of the atmosphere, than rays striking at a large angle. The longer the path of the sun’s rays, the greater is the amount of reflection and absorption of heat by the atmosphere. As a result, the intensity of insolation at one place is less.
