Question

The chief reason the equatorial regions are warmer than the polar regions is that

a. the equator is closer to the sun

b. sunlight falls more nearly vertically on the equatorial regions

c. sunlight is reflected by ice and snow in the polar regions

d. there is more CO2 in the air over the equatorial regions

Answer 1

The shape of the earth is spherical. The line which cuts the earth into half is called equatorial line. The rays from the sun come and fall on the equator directly and make its climate hot and wet. Sun rays that reach polar region will be slow when compared to that of the equator, thus polar region will be cold compared to the equatorial region. 

 

Thus, correct answer is (b).

Thus, correct answer is (b).
