A continent is one of several very large landmasses on Earth. They are generally identified by convention rather than any strict criteria, with seven regions commonly regarded as continents—they are (from largest in size to smallest): Asia, Africa, North America, South America, Antarctica, Europe, and Australia.
Plate tectonics is the geological process and study of the movement, collision and division of continents, earlier known as continental drift.

Famous quotes containing the word continent:
“Other nations have tried to check ... the fulfillment of our manifest destiny to overspread the continent allotted by Providence for the free development of our yearly multiplying millions.”
—John Louis O’Sullivan (1813–1895)
“The land is the appointed remedy for whatever is false and fantastic in our culture. The continent we inhabit is to be physic and food for our mind, as well as our body. The land, with its tranquilizing, sanative influences, is to repair the errors of a scholastic and traditional education, and bring us to just relations with men and things.”
—Ralph Waldo Emerson (1803–1882)
“What a prodigious growth this English race, especially the American branch of it, is having! How soon will it subdue and occupy all the wild parts of this continent and of the islands adjacent. No prophecy, however seemingly extravagant, as to future achievements in this way [is] likely to equal the reality.”
—Rutherford Birchard Hayes (1822–1893)
