Introduction:
The Earth receives solar radiation from the sun that is responsible for the heating of the planet's surface and atmosphere. However, not all regions of the Earth receive the same amount of heat. The torrid zone, also known as the equatorial region, receives the maximum amount of heat compared to other regions on the planet.

Reasons for maximum heat:
The following are the reasons why the torrid zone receives the maximum amount of heat:

1. Angle of incidence: The angle of incidence of solar radiation is nearly perpendicular to the Earth's surface in the torrid zone. This means that the sunlight that falls on the equatorial region is more concentrated and intense than in other regions.

2. Tilt of the Earth's axis: The tilt of the Earth's axis causes the sun's rays to be more concentrated in the torrid zone during the summer months. This results in a longer duration of daylight and more direct sunlight, leading to higher temperatures.

3. Less atmospheric interference: The torrid zone is located near the center of the Earth, where there is less atmospheric interference. This means that the sunlight that reaches the equatorial region is less scattered and absorbed by the atmosphere, resulting in more heat.

4. Ocean currents: The ocean currents in the torrid zone also contribute to the region's high temperatures. The warm ocean currents transport heat from the equator to other regions, contributing to the overall warming of the planet.

Conclusion:
The torrid zone receives the maximum amount of heat due to its location on the Earth's surface, the angle of incidence of solar radiation, the tilt of the Earth's axis, less atmospheric interference, and ocean currents. These factors combine to make the equatorial region the hottest region on the planet.

The mid-day sun is exactly overhead at least once a year on all latitudes in between the Tropic of Cancer and the Tropic of Capricorn. This area, therefore, receives the maximum heat and is called the Torrid Zone.
