What are the three heat zones of the Earth?

Answer: There are three heat zones of the Earth based on the sun’s rays: the Torrid Zone, the Temperate Zone, and the Frigid Zone. The Torrid Zone is near the equator and receives direct sunlight. The Temperate Zones have moderate temperatures, while the Frigid Zones remain cold due to slanting sunrays.

Explanation:

The Earth is divided into three major heat zones based on how sunlight falls on different parts of the planet due to its spherical shape and tilted axis. The three heat zones of the Earth are:

1. Torrid Zone: This is the hottest zone, located between the Tropic of Cancer (23.5°N) and the Tropic of Capricorn (23.5°S). It receives direct and vertical sunlight throughout the year because it lies near the equator. As a result, temperatures remain high, and regions here often experience tropical climates. Countries like Brazil, India, and Indonesia fall in this zone.
   
2. Temperate Zones: These lie 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 sun’s rays are slanted, so these regions receive moderate heat. They have four distinct seasons: spring, summer, autumn, and winter. Much of Europe, North America, and parts of Australia lie in the temperate zones.
   
3. Frigid Zones: These are the coldest parts of the Earth, found near the poles, from the Arctic Circle (66.5°N) to the North Pole, and the Antarctic Circle (66.5°S) to the South Pole. The sun’s rays here are highly slanted or may not reach the surface for long periods, especially during winter. These areas are covered with ice and snow for most of the year and experience extremely cold temperatures.
