Where Does the Equator Cross South America? Clarifying the Geography

The equator crosses the northern part of South America—not the southern part. It passes through four countries:

1. Ecuador (the country is named for it)
2. Colombia
3. Brazil (northern Amazon region)
4. Peru (just north of Iquitos)

The equator does not touch Chile, Argentina, Uruguay, Paraguay, Bolivia, or the southern cone. The Tropic of Capricorn (23.5°S) crosses the southern part of the continent (Chile, Argentina, Paraguay, Brazil).
