The five main latitude regions of Earth's surface comprise geographical zones, divided by the major circles of latitude. The differences between them relate to climate. They are as follows:
- The North Frigid Zone, between the North Pole at 90° N and the Arctic Circle at 66°33′49.9″ N, covers 4.12% of Earth's surface.
- The North Temperate Zone, between the Arctic Circle at 66°33′49.9″ N and the Tropic of Cancer at 23°26′10.1″ N, covers 25.99% of Earth's surface.
- The Torrid Zone, between the Tropic of Cancer at 23°26′10.1″ N and the Tropic of Capricorn at 23°26′10.1″ S, covers 39.78% of Earth's surface.
- The South Temperate Zone, between the Tropic of Capricorn at 23°26′10.1″ S and the Antarctic Circle at 66°33′49.9″ S, covers 25.99% of Earth's surface.
- The South Frigid Zone, from the Antarctic Circle at 66°33′49.9″ S and the South Pole at 90° S, covers 4.12% of Earth's surface.
