What is the primary reason that the air above the equators heated more than other places on earth?

Question

The sun hits the equator more often due to the shape of the earth
of the Earth on its axis causes more sunlight to reach the equator
There are more water around the equator and anywhere else on earth
The sunlight, the equator more angle

Answer 1

The primary reason that the air above the equator heats more than in other places on Earth is:

The tilt of the Earth on its axis causes more sunlight to reach the equator.

At the equator, the sun's rays shine more directly throughout the year, resulting in higher temperatures compared to higher latitudes, where the rays strike the Earth at a less direct angle. This direct exposure leads to increased warming in equatorial regions.
