The heat zones of the Earth are determined by the latitude and the angle at which the sun’s rays hit the Earth’s surface.
There are three main heat zones of the Earth: the Torrid Zone, the Temperate Zone, and the Frigid Zone.
- The Torrid Zone: This zone is located between the Tropic of Cancer and the Tropic of Capricorn, which is roughly between 23.5 degrees north and south of the equator. The Torrid Zone receives the most direct sunlight throughout the year, which results in a hot and humid climate.
- The Temperate Zone: This zone is located between the Tropic of Cancer and the Arctic Circle in the Northern Hemisphere and the Tropic of Capricorn and the Antarctic Circle in the Southern Hemisphere. The Temperate Zone receives varying amounts of direct sunlight throughout the year, which results in a range of climates from mild to moderate.
- The Frigid Zone: This zone is located near the poles, which is above the Arctic Circle in the Northern Hemisphere and below the Antarctic Circle in the Southern Hemisphere. The Frigid Zone receives very little direct sunlight throughout the year, which results in a cold and harsh climate.
