Theory:

Latitude lines help divide the earth into different climatic zones based on the amount of heat received from the Sun.
Torrid Zone
Torrid Zone is a region between
Equator to the Tropic of Cancer (\(23½°N\)) in the northern hemisphere and Equator to the Tropic of Capricorn (\(23½°S\)) in the southern hemisphere
or in other words region between Tropic of Cancer and Tropic of Capricorn
  • Solar radiation falls vertically.
  • Very high average temperature.
  • Therefore, this region is known as the Torrid Zone.

Temperate Zone
Northern Hemisphere: From the Tropic of Cancer (23½°N) to the Arctic Circle (66½°N)
Southern Hemisphere: From the Tropic of Capricorn (23½°S) to the Antarctic Circle (66½°S)
  • The Solar radiation reaches the ground slantingly (i.e. inclined)
  • Moderate temperature prevails in this region. Hence, this region is called the Temperate Zone.
Frigid Zone
Northern hemisphere: From the Arctic Circle (66½°N) to the North Pole (90°N)
Southern hemisphere: From the Antarctic Circle (66½°S) to the South Pole (90°S)
  • The Solar radiation fall at a very small angle (nearly flat) throughout the year.
  • The temperature is very low mostly freezing. Therefore, this region is known as Frigid Zone.
