There are a few reasons why the equator is the hottest place on Earth. One reason is that it receives more direct sunlight than any other location on the planet. The sun’s rays hit the Earth at a perpendicular angle at the equator, which means that more of the sun’s energy reaches this region than any other. Additionally, there is very little variation in temperature at the equator throughout the year. This lack of temperature variation results in less heat being lost to cooler air or water, making it one of the warmest places on Earth.
Another reason why the equator is so hot has to do with its location relative to large bodies of water. The ocean helps regulate global temperatures by absorbing and releasing heat, and areas near large bodies of water tend to be warmer than those further inland. Because much of Earth’s landmass is located near or above latitude 30Â° N/S (the Tropic of Cancer and Tropic of Capricorn), there is less landmass near or below latitude 0Â° (the equator) where heat can be released into cooler air or water masses. This results in higher average temperatures at lower latitudes like those found near the equator.
Finally, atmospheric circulation plays a role in determining temperatures around different parts of Earth’s surface. Warm air rises from low latitudes towards higher latitudes while cool air sinks from high latitudes towards lower ones in what are known as Hadley cells . These cells help redistribute heat around our planet, but they also serve to trap heat near low latitudes like those found at or close to the equator resulting in higher average temperatures compared to other parts of Earth .
