Regions around the equator have the warmest climate due to the direct and focused sun rays they receive. The sun's rays hit the equator at a more perpendicular angle compared to areas farther away, resulting in a more concentrated transfer of heat energy. This concentrated heat energy warms the land and atmosphere, making the equatorial regions consistently warmer than the poles or other latitudes.

In contrast, places far from the equator receive less heat because the sun's rays strike their surfaces at an oblique angle. When sunlight spreads over a larger area, the heat energy is dispersed, and the overall temperature of the region is lower. This is why the poles and areas closer to them experience colder climates.

Here's a more detailed explanation of the factors that contribute to the temperature difference:

In summary, the combination of a direct angle of sunlight, a thinner atmosphere, and longer daylight hours contributes to the warmer climate experienced in regions around the equator.

The sun's rays are the most concentrated around the equator. Moving north or south of the equator, the sun's rays are spread over a larger area, so each square meter of Earth's surface receives less solar energy. This is because of the angle of the sun's rays as they strike Earth's curved surface. Due to the spherical shape of the Earth, sunlight falls on different parts at different angles. Direct and focused sun rays falls on the equator and hence, the regions here are hotter and warmer. At higher latitudes, the angle that the sun's rays hit Earth is lower due to Earth's curved shape. This causes the sun's energy to be spread over a larger surface area, which results in lower overall temperatures north and south of the equator. The Sun rays fall straight on the areas lying near equator. and the places which are far away from the equator get less amount of heat as only some rays can strike on the areas. It is due to the tilting of the earth's axis and the shape of the earth. They receive less amount of heat. The distance from the equator affects the climate of a place. At the poles, energy from the sun reaches the Earth's surface at lower angles and passes through a thicker layer of atmosphere than at the equator. This means the climate is cooler further from the Equator.
