At which location would sunlight have to pass through the thickest amount of atmosphere before reaching earth's surface? a. at the poles b. at the equator c. at the subtropical latitudes d. at latitudes between 50 and 80 degrees

Option (A)

Explanation: The poles are located at the two extreme ends of both the hemisphere, namely the north pole and the south pole.

The sunlight is not directly incident on the poles as the poles are at far distance and the sunlight has to penetrate through the thick atmospheric cloud, which obstructs its light to pass through. So it does not reach the poles and even if the sunlight reaches the poles after passing through the entire atmosphere, it does not have any effect on them.

Whereas at the equatorial region, tropical and sub-tropical region, the sunlight does not face much obstruction and easily reaches the earth's surface.

Thus, the correct answer is option (A).
