A continent is one of several very large landmasses. Generally identified by convention rather than any strict criteria, up to seven regions are commonly regarded as continents. Ordered from largest in area to smallest, they are: Asia, Africa, North America, South America, Antarctica, Europe, and Australia.
Other terms include Eurasia (Europe and Asia) and the Americas/America (North America and South America).
(Other) islands are frequently grouped with a neighboring continent to divide all the world's land into geopolitical regions. 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 geopolitical region called Oceania.
"Continental Europe" or "mainland Europe", sometimes "the Continent", may refer to the contiguous continent of Europe, excluding its surrounding islands, possibly also excluding other areas. "The Continent" may also be used locally in a country to refer to the part of the country that is in mainland Europe.
"Continental races" is a sometimes used phrase for major races, which may be justified for races such as Amerindians, Australoids, and Europeans, but less so for races such as East Asians and Sub-Saharan Africans.
