Western hemisphere

The western hemisphere, also Western Hemisphere,^[1] is a geographical term for the half of the Earth that lies west of the Prime Meridian (which crosses Greenwich, England), the other half being the eastern hemisphere.[1] Less properly, it can refer to the Americas (or the New World) and adjacent waters, while excluding other territories that lie geographically in the hemisphere (parts of Africa, Europe, Antarctica, and Asia). Western hemisphere is sometimes used as an equivalent for the geopolitical construct, the Western World, which typically includes the Americas and Western/Central Europe.

A hemisphere is a geometric term that literally means "half of a sphere", and in geography the term is used when dividing the Earth into two halves. The most obvious dividing line is the equator, creating the northern and southern hemispheres. These hemispheres are based on unambiguous reference points — the north and south poles — which are defined by the Earth's axis of rotation and, in turn, define the equator. Any definition of eastern and western hemispheres, however, requires the sextion of an arbitrary meridian and a corresponding meridian on the other side of the Earth. The Prime Meridian at 0° longitude is typically used, which runs through Greenwich (London) in the United Kingdom; this is used to define the International Date Line (or End Meridian) on the other side of the Earth at 180° longitude. In its proper geographic sense, the western hemisphere includes not only the Americas, but the western portions of Europe and Africa, the easternmost tip of Russia, numerous territories in Oceania, and a portion of Antarctica while excluding some of the Aleutian Islands to the southwest of the Alaskan mainland.
