Geographical zone. The five main latitude regions of Earth's surface comprise geographical zones, [1] 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′50.1″ N, covers 4.12% of Earth's surface.
The United Nations geoscheme is a system which divides 248 countries and territories in the world into six continental regions, 22 geographical subregions, and two intermediary regions. [ 1] It was devised by the United Nations Statistics Division (UNSD) based on the M49 coding classification. [ 2] The creators note that "the assignment of ...
The United Nations geoscheme was created for statistical analysis and consists of six continental regions, 22 geographical subregions, and two intermediary regions. [2]The United Nations Statistics Division created and maintains the M49 – Standard country or area codes for statistical use. [3]
World map. A world map is a map of most or all of the surface of Earth. World maps, because of their scale, must deal with the problem of projection. Maps rendered in two dimensions by necessity distort the display of the three-dimensional surface of the Earth. While this is true of any map, these distortions reach extremes in a world map.
The geographical centre of Earth is the geometric centre of all land surfaces on Earth. Geometrically defined it is the centroid of all land surfaces within the two dimensions of the Geoid surface which approximates the Earth's outer shape. The term centre of minimum distance [1] specifies the concept more precisely as the domain is the sphere ...
Region. In geography, regions, otherwise referred to as areas, zones, lands or territories, are portions of the Earth's surface that are broadly divided by physical characteristics ( physical geography ), human impact characteristics ( human geography ), and the interaction of humanity and the environment ( environmental geography ).
Earth is the third planet from the Sun and the only astronomical object known to harbor life. This is enabled by Earth being an ocean world, the only one in the Solar System sustaining liquid surface water. Almost all of Earth's water is contained in its global ocean, covering 70.8% of Earth's crust.
World map with the intertropical zone highlighted in crimson Areas of the world with tropical climates. The tropics are the regions of Earth surrounding the Equator.They are defined in latitude by the Tropic of Cancer in the Northern Hemisphere at 23°26′09.9″ (or 23.43609°) N and the Tropic of Capricorn in the Southern Hemisphere at 23°26′09.9″ (or 23.43609°) S.
