why is the equator region the hottest part of the earth's surface?

Question

-the equator region is closest to the sun
-the equator region has the widest diameter.
-the sun shines directly on the equator region
-the rays of the sun hit the equator region at an angle

Answer 1

The correct reason why the equator region is the hottest part of the Earth's surface is:

The sun shines directly on the equator region.

At the equator, the sun's rays strike the Earth more directly compared to regions farther from the equator, where the rays hit at a steeper angle and spread over a larger area, resulting in less heat concentration. This direct sunlight leads to higher temperatures in equatorial regions.
