What is "geographical zone"

n. any of the regions of the surface of the Earth loosely divided according to latitude or longitude [syn: zone]

The five main latitude regions of the 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 Arctic Circle 66.5 degrees north and the North Pole 90 degrees north. Covers 4.12% of Earth's surface
• The North Temperate Zone, between the Tropic of Cancer 23.5 degrees north and the Arctic Circle 66.5 degrees north. Covers 25.99% of Earth's surface
• The Torrid Zone, between the Tropic of Cancer 23.5 degrees north and the Tropic of Capricorn 23.5 degrees south. Covers 39.78% of Earth's surface
• The South Temperate Zone, between the Tropic of Capricorn 23.5 degrees south and the Antarctic Circle 66.5 degrees south. Covers 25.99% of Earth's surface
• The South Frigid Zone, from Antarctic Circle 66.5 degrees south and the South Pole 90 degrees south. Covers 4.12% of Earth's surface.
