The tropics are defined as the region between the Tropic of Cancer in the Northern Hemisphere at 23°26′09.8″ (or 23.43605°) N and the Tropic of Capricorn in the Southern Hemisphere at 23°26′09.8″ (or 23.43605°) S; [8] these latitudes correspond to the axial tilt of the Earth. The Tropic of Cancer is the Northernmost latitude from ...
The Torrid Zone, between the Tropic of Cancer at 23°26′09.8″ N and the Tropic of Capricorn at 23°26′09.8″ S, covers 39.78% of Earth's surface. The South Temperate Zone, between the Tropic of Capricorn at 23°26′09.8″ S and the Antarctic Circle at 66°33′50.2″ S, covers 25.99% of Earth's surface.
Knowledge of precise climatic events decreases as the record goes further back in time. The timeline of glaciation covers ice ages specifically, which tend to have their own names for phases, often with different names used for different parts of the world. The names for earlier periods and events come from geology and paleontology.
Tropical climates normally have only two seasons, a wet season and a dry season. Depending on the location of the region, the wet and dry seasons can have varying duration. Annual temperature changes in the tropics are small. Due to the high temperatures and abundant rainfall, much of the plant life grows throughout the year.
Tropical geography refers to the study of places and people in the tropics. When it first emerged as a discipline, tropical geography was closely associated with imperialism and colonial expansion of the European empires as contributing scholars tended to portray the tropical places as "primitive" and people "uncivilised" and "inferior".

The Tropic of Capricorn's position is not fixed, but constantly changes because of a slight wobble in the Earth's longitudinal alignment relative to its orbit around the Sun. Earth's axial tilt varies over a 41,000 year period from about 22.1 to 24.5 degrees and currently resides at about 23.4 degrees. This wobble means that the Tropic of ...
The original and most common aspect of the Mercator projection for maps of the Earth is the normal aspect, for which the axis of the cylinder is the Earth's axis of rotation which passes through the North and South poles, and the contact circle is the Earth's equator.
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.
