Heat zones of the earth: The fact that the earth is spherical in shape results in different parts of the earth getting heated differently. Based on the heat received from the sun, Earth is divided into three heat zones.
They are
1. Torrid Zone: It is a region between the tropic of cancer and the tropic of Capricorn. This region receives the direct rays of the sun and gets the maximum heat from the sun. This zone known as the torrid or the tropical zone
2. Temperate zone: This zone lies between the Tropic of cancer and the Arctic circle in the Northern Hemisphere and between the Tropic of Capricorn and the Antartic circle in the southern Hemisphere. This zone gets the slanting rays of the sun and the angle of the sun’s rays goes on decreasing towards as the poles. Thus this zone experiences moderate temperature.
3. Frigid Zone: The frigid zone lies between the Arctic circle and the North Pole and between the Antartic circle and the South Pole. This region also known as Polar region. Since it receives the extremely low temperature throughout the year,these regions are covered with snow.
