Amerigo VespucciThe word America was first used to describe this part of the globe in 1507. The name honors the Italian explorer Amerigo Vespucci. We citizens of the United States aren't the only ones from America, though. "The Americas" refers to all parts of North, Central and South America -- and the Caribbean islands too.

All together -- the Americas account for about 8 percent of the Earth's total surface -- and 14 percent of its people.

Now -- next month President Barack Obama will attend the Summit of the Americas.

The question is: Where will the summit take place?

Is it (a) Washington (b) Port of Spain or (c) Quebec City?
