Air above the equator is heated more than at any other place on earth because solar rays strike the equator a. at a 180° angle c. more directly b. at a 45° angle d. none of the above

Ans C)

The earth is tilted at an angle of 23.5 ° with respect to the sun. This impacts the extent to which the equator gets heated up compared to the north and south poles. As the earth orbits around the sun, the regions in the equator receive direct sunlight which causes the air above the equator to heat up. In contrast, the tilt causes either the north or the south pole to receive the rays from the sun which in turn is responsible for change of seasons in the poles.

Thus, air above the equator is heated more than at any other place on Earth because solar rays strike the equator more directly.
