What do the locations of many of the cities on the map of the Western Hemisphere have in common? Why are these locations significant?

The Western Hemisphere is a geographical term for the half of Earth which lies west of the prime meridian (which crosses Greenwich, London, United Kingdom) and east of the antimeridian. The other half is called the Eastern Hemisphere. It may be used in a cultural or geopolitical sense as a synonym for the "New World".

The Western Hemisphere consists of the Americas, the western portions of Europe and Africa, the extreme eastern tip of Siberia (Russia), numerous territories in Oceania, and a portion of Antarctica, while excluding some of the Aleutian Islands to the southwest of the Alaskan mainland.

The center of the Western Hemisphere is located in the Pacific Ocean at the intersection of the 90th meridian west and the Equator, among the Galápagos Islands. The nearest land is Genovesa Island at 0°19′00″N 89°57′00″W.

The highest mountain in the Western Hemisphere is Aconcagua in the Andes of Argentina at 6,960.8 metres (22,837 ft).

The tallest human-occupiable building or tower in the Western Hemisphere is the CN Tower, which is located in Toronto, Canada at 43°38′33.22″N 79°23′13.41″W.

Proposed revision of hemispheric bordersEdit

In an attempt 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.
