Here's why:
* Angle of Incidence: The sun's rays hit the Earth at a more direct angle near the equator, meaning the energy is concentrated over a smaller area. This leads to higher temperatures.
* Length of Day: Daylight hours are relatively consistent throughout the year near the equator, resulting in more overall solar radiation received.
* Atmosphere: The atmosphere is thinner near the equator, allowing more solar radiation to reach the surface.
While the tropics receive the most direct solar radiation, it's important to note that the total amount of solar radiation received at the Earth's surface varies depending on factors like cloud cover, season, and time of day.
