Temperate Regions
摘要
The temperate regions of both hemispheres comprise a wide strip of the planet between the Arctic Circle (66° 23′ N) and the Tropic of Cancer (23° 27′ N) in the northern hemisphere, and between the Antarctic Circle (66° 23′ S) and the Tropic of Capricorn (23° 27′ S) in the southern hemisphere. The temperate regions cover approximately 25% of the Earth’s surface and are characterized by their wide geographical diversity.
