The continents located in the southern hemisphere are Australia, Antarctica, Africa and South America. Parts of Africa and South America are also located in the northern hemisphere.
The southern hemisphere encompasses the half of the planet below the equator. Because of Earth's rotation, winter occurs in the southern hemisphere from June 21 to Sept. 21. Summer occurs from Dec. 21 to March 21.
The southern hemisphere has significantly less pollution than the northern hemisphere because of lower population densities. Smaller land masses and lower levels of industrialization are also true of the southern hemisphere. Because of the Coriolis effect, hurricanes and tropical storms spin clockwise in the southern hemisphere.
