Earth's western hemisphere showing topography relative to Earth's center instead of to mean sea level, as in common topographic maps. Earth has a rounded shape, through hydrostatic equilibrium, [85] with an average diameter of 12,742 kilometres (7,918 mi), making it the fifth largest planetary sized and largest terrestrial object of the Solar ...
Hemispheres of Earth. In geography and cartography, hemispheres of Earth are any division of the globe into two equal halves (hemispheres), typically divided into northern and southern halves by the Equator and into western and eastern halves by the Prime meridian. Hemispheres can be divided geographically or culturally, or based on religion or ...
The centre of the water hemisphere is the antipode of the centre of the land hemisphere, and is therefore located at (near New Zealand's Bounty Islands in the Pacific Ocean An alternative assignment determines the centre of the land hemisphere to be at 47°24′42″N 2°37′15″W / 47.411667°N 2.620833°W / 47.411667; -2.620833 ...
The Eastern Hemisphere is the half of the planet Earth which is east of the prime meridian (which crosses Greenwich, London, United Kingdom) and west of the antimeridian (which crosses the Pacific Ocean and relatively little land from pole to pole). It is also used to refer to Afro-Eurasia (Africa and Eurasia) and Australia, in contrast with ...
The Southern Hemisphere from above the South Pole. The Southern Hemisphere is highlighted in yellow. The hemispheres appear to be unequal in this image because Antarctica is not shown. The Southern Hemisphere is the half (hemisphere) of Earth that is south of the Equator. It contains all or parts of five continents [1] (the whole of Antarctica ...
The Western Hemisphere is the half of the planet Earth that lies west of the Prime Meridian —which crosses Greenwich, London, England —and east of the 180th meridian. [1][2] The other half is called the Eastern Hemisphere. Geo-politically, the term Western Hemisphere is often used as a metonym for the Americas or the "New World", even ...
Northern hemisphere glaciation during the last ice ages. The setup of 3 to 4 kilometer thick ice sheets caused a sea level lowering of about 120 m. The Arctic is a region around the North Pole (90° latitude). Its climate is characterized by cold winters and cool summers. Precipitation mostly comes in the form of snow.
A globe is a spherical model of Earth, of some other celestial body, or of the celestial sphere. Globes serve purposes similar to maps, but, unlike maps, they do not distort the surface that they portray except to scale it down. A model globe of Earth is called a terrestrial globe. A model globe of the celestial sphere is called a celestial globe.
