THE CONTINENTS

DEFINITION OF CONTINENT
A continent is one of several very large landmasses on Earth. They are generally identified by convention rather than any strict criteria, with up to seven regions commonly regarded as continents. These are (from largest in size to smallest): Asia, Africa, North America, South America, Antarctica, Europe, and Australia.[1] In geology, areas of continental crust include regions covered with water.
