Heat Zones of the Earth

Temperature Zones of the Earth

Due to the tilted nature of the Earth's axis, there is an unequal distribution of heat or solar energy on the surface of the Earth. T he amount of heat a place gets depends on the angle of incidence of the Sun's rays (solar energy) at that point. Based on the amount of solar energy received, each hemisphere is divided into three temperature or heat zones - the torrid zone, the temperate zone and the frigid zone.

Torrid Zone:

As the Earth revolves around the Sun, due to the tilted nature of the Earths axis, the Sun appears to move between the Tropic of Cancer and the Tropic of Capricorn. In the latitudes between the two tropics, the mid-day Sun shines perpendicularly overhead at least once a year. As these latitudes get the direct rays of the Sun, this is the hottest zone. This zone is known as the torrid zone or the tropical zone. No place beyond the tropics gets the direct rays of the Sun. Most of southern India lies in the torrid zone. 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.
