Blank political map of South America and Central America.

- The image displays the outlines of countries in North and South America.
- The task is to identify the country that is entirely within the Southern Hemisphere.
- Among all the countries shown, only Chile extends significantly into the Southern Hemisphere.
- However, Chile's northernmost point is just south of the equator, meaning a small part of it may be in the Northern Hemisphere.
- Upon closer inspection, the only country that lies completely south of the equator is Chile, if we consider its mainland and exclude its overseas territories like Easter Island (which is also in the Southern Hemisphere).
- But actually, Chile’s northern border is at approximately 17°S, so its entire territory is in the Southern Hemisphere.
- Therefore, the correct answer is Chile.
