![]() ![]() In geology, a continent is defined as "one of Earth's major landmasses, including both dry land and continental shelves". Under this scheme, most of the island countries and territories in the Pacific Ocean are grouped together with the continent of Australia to form a geographical region called Oceania. Oceanic islands are frequently grouped with a nearby continent to divide all the world's land into geographical regions. Zealandia, a largely submerged mass of continental crust, has also been described as a continent. Variations with fewer continents may merge some of these, for example America, Eurasia, or Afro-Eurasia are sometimes treated as single continents, which can bring the total number as low as four. Ordered from largest in area to smallest, these seven regions are: Asia, Africa, North America, South America, Antarctica, Europe, and Australia. Generally identified by convention rather than any strict criteria, up to seven geographical regions are commonly regarded as continents. Depending on the convention and model, some continents may be consolidated or subdivided: for example, Eurasia is most often subdivided into Asia and Europe (red shades), while North and South America are sometimes recognised as one American continent (green shades)Ī continent is any of several large landmasses.
