Which country is closest to the US Ecuador Puerto Rico cuba panama?
Ecuador is the Spanish word meaning Equator. Ecuador has the the
Equator running right through it.
Panama is just north of Colombia, which is just north of Ecuador
so it is the next closest country to the equator.
Puerto Rico is Part of the United States but assuming that
Puerto Rico is being treated separately, and the actual "Lower 48"
US States is what is meant by The US. Puerto Rico is next. Then the
US.
However this is a trick question! The US has territories closer
to the Equator than Puerto Rico, and even closer than the country
of Panama. Baker Island at 0°11.7′N has the equator running through
its territorial waters!
