Actually I learned in school that there is actually only 1 American continent.. From Ushuaia to Alaska.. But I learned the bad way that in the US they teach the kids that there are 2 Americas.. North and south.. .. Here is some text I found online about the topic...
A continent is one of several major land masses on the earth. There is no standard definition for the number of continents but you'll commonly find that the numbers six or seven are used. By most standards, there are a maximum of seven continents - Africa, Antarctica, Asia, Australia, Europe, North America, and South America. Most students in the U.S. are taught that there are seven continents.
In Europe and South America, many students are taught about six continents, where North and South America is combined to form a single America. Thus, these six continents are Africa, America, Antarctica, Asia, Australia, and Europe.
I can add that I also learned that Australia is a country.. The continent is Oceania that includes several other countries..
