How many continents are part of the Western Hemisphere?
Arguably, all continents but Australia are a part of the Western
Hemisphere. This means Europe, Africa, Asia, North America, and
South America are a part of the Western Hemisphere; South America
is the only continent fully in the Western Hemisphere. However,
Australia is usually included with Oceania as a continent, and the
region of Oceania is a part of the Western Hemisphere, so
technically, all continents are a part of the Western
Hemisphere.
