South America is (3) both north and south of the equator.

Here's why:

* The Equator: The equator is an imaginary line that circles the Earth at 0 degrees latitude.

* South America's Location: A large portion of South America lies south of the equator, but the northernmost parts of countries like Colombia, Venezuela, Guyana, Suriname, and French Guiana are actually north of the equator.
