Torrid zone: It is a region between the Tropic of Cancer and the Tropic of Capricorn. This region receives the direct vertical rays of the sun for almost the whole year. Therefore, this zone gets maximum heat from the Sun. This zone is known as the torrid or the tropcal zone.

Temperate Zone: This zone lie between the Tropic of Cancer and the Arctic Circle in the Northern Hemisphere and between Tropic of Capricorn and the Antarctic Circle in the southern hemisphere. This zone gets the slanting rays of the Sun as the angle of the Sun’s rays goes on decreasing towards the Poles. Thus this zone experiences moderate temperature.

Frigid Zone:  The frigid zone lies between the Arctic Circle and the North pole and between the Antarctic Circle and the South Pole. This zone is also known as the Polar region. Since it receives the extreme slanting rays of the Sun, the temperature is extremely low throughout the year. This is the reason that the polar regions are generally covered with ice.
