The northern one is called the Tropic of Cancer, and the southern is the Tropic of Capricorn. As the Earth's axial tilt changes, [a] so too do the tropical and polar circles. The tropics constitute 39.8% of Earth's surface area [1] and contain 36% of Earth's landmass. [2]
The relative position of the Sun is a major factor in the heat gain of buildings and in the performance of solar energy systems. [1] Accurate location-specific knowledge of sun path and climatic conditions is essential for economic decisions about solar collector area, orientation, landscaping, summer shading, and the cost-effective use of ...
The North Temperate Zone, between the Arctic Circle at 66°33′50.3″ N and the Tropic of Cancer at 23°26′09.7″ N, covers 25.99% of Earth's surface. The Torrid Zone, between the Tropic of Cancer at 23°26′09.7″ N and the Tropic of Capricorn at 23°26′09.7″ S, covers 39.78% of Earth's surface.
Cellular Oncology is a bimonthly peer-reviewed medical journal published by Springer Science+Business Media. [1] The journal was established in 1989 as Analytical Cellular Pathology, obtaining its current name in 2003.
Tropical ecology is the study of the relationships between the biotic and abiotic components of the tropics, or the area of the Earth that lies between the Tropic of Cancer and the Tropic of Capricorn (23.4378° N and 23.4378° S, respectively). The tropical climate experiences hot, humid weather and rainfall year-round.
