Western Hemisphere, part of Earth comprising North and South America and the surrounding waters. Longitudes 20° W and 160° E are often considered its boundaries. Some geographers, however, define the Western Hemisphere as being the half of Earth that lies west of the Greenwich meridian (prime meridian, 0° longitude) continuing to the 180th meridian. According to this scheme, the Western Hemisphere includes not only North and South America but also portions of Africa, Europe, Antarctica, and Asia.
