Africa stretches through both the Northern and Southern hemispheres, as well as the Eastern and Western hemispheres.

Antarctica is in the South Pole, and within the Southern Hemisphere. It extends through the Eastern and Western hemispheres.

Asia, like Africa, extends through all hemispheres. It is mostly within the Northern and Eastern hemispheres, but part of it (Indonesia, which is considered a part of the Asian continent) goes into the Southern Hemisphere, while another part, Russia, extends through the Eastern hemisphere, and onward to the Western hemisphere.

Australia is within the Southern and Eastern hemispheres only.

Europe is mostly situated within the Eastern hemisphere, but entirely within the Northern hemisphere: the United Kingdom, France and Spain stretch into both the Eastern and Western hemispheres, while Portugal and Ireland are completely within the Western hemisphere.

North America is situated entirely within the Northern hemisphere, and it also within the Western Hemisphere.

South America-- the equator crosses through it, so it is in both the Northern and Southern hemispheres, and entirely within the Western hemisphere
