Here's why:
* Earth's Tilt: Earth is tilted on its axis at approximately 23.5 degrees. This tilt is responsible for the seasons.
* Equator's Position: The Equator is an imaginary line that circles the Earth at 0 degrees latitude. It's the point where the Earth's axis intersects the Earth's surface.
* Solar Angle: Because of the Earth's tilt, the Equator receives sunlight at the most direct angle throughout the year. This means the sun appears high in the sky and the rays hit the Earth closer to perpendicular.
Note: The sun's angle can vary slightly throughout the year even at the Equator due to the Earth's elliptical orbit and the tilt of the axis. However, overall, the Equator experiences the most direct sunlight compared to other locations on Earth.
