The WESTERN HEMISPHERE is a geographical term for the half of the earth which lies west of the Prime meridian (which crosses Greenwich , UK ) and east of the antimeridian . The other half is called the Eastern Hemisphere .
In this sense, the Western Hemisphere consists of the Americas , the western portions of Eurasia and Africa , the extreme eastern 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.
In an effort to define the Western Hemisphere as the parts of the world which are not part of the Old World , there also exist projections which use the 20th meridian west and the diametrically opposed 160th meridian east to define the hemisphere. This projection excludes the European and African mainlands and a small portion of northeast Greenland , but includes more of eastern Russia and Oceania.
COUNTRIES IN BOTH HEMISPHERES
Below is a list of the countries which are in both the Western and Eastern Hemispheres on the IERS Reference Meridian , in order from north to south:
* Denmark (due to Greenland and the Faroe Islands ; mainland Denmark lies entirely in the Eastern Hemisphere). * Norway (due to Jan Mayen ; mainland Norway lies entirely in the Eastern Hemisphere). * United Kingdom * Netherlands (The islands of the Caribbean Netherlands lie entirely within the Western Hemisphere while the European Netherlands lies entirely in the Eastern Hemisphere.) * France * Spain * Algeria * Mali * Burkina Faso * Togo * Ghana
Below is a list of the countries which are in both the Western and Eastern Hemispheres along the 180th meridian , in order from north to south:
