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 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 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 ...
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 Americas make up most of the land in Earth's Western Hemisphere. [54] The northernmost point of the Americas is Kaffeklubben Island, which is the most northerly point of land on Earth. [55] The southernmost point is the islands of Southern Thule, although they are sometimes considered part of Antarctica. [56]
The Columbian exchange, also known as the Columbian interchange, was the widespread transfer of plants, animals, precious metals, commodities, culture, human populations, technology, diseases, and ideas between the New World (the Americas) in the Western Hemisphere, and the Old World (Afro-Eurasia) in the Eastern Hemisphere, in the late 15th and following centuries.

A prime meridian is an arbitrarily chosen meridian (a line of longitude) in a geographic coordinate system at which longitude is defined to be 0°. Together, a prime meridian and its anti-meridian (the 180th meridian in a 360°-system) form a great circle. This great circle divides a spheroid, like Earth, into two hemispheres: the Eastern ...
Russia, New Zealand, and Fiji have most of their territories west of the 180th meridian, in the Eastern Hemisphere, so they are considered in this article to belong to the easternmost countries with their territory stretching east beyond the 180th meridian into the Western Hemisphere. Conversely, the United States and Kiribati have most of ...
