​what are continents

​A continent is one of several large landmasses. Generally identified by convention rather than any strict criteria, up to seven geographical regions are commonly regarded as continents. Ordered from largest in area to smallest, these seven regions are: Asia, Africa, North America, South America, Antarctica, Europe, and Australia.

​Asia

​Asia is Earth's largest and most populous continent, located primarily in the Eastern and Northern Hemispheres. It shares the continental landmass of Eurasia with the continent of Europe and the continental landmass of Afro-Eurasia with both Europe and Africa.

​Africa

Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km² including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area. With 1.3 billion people as of 2018, it accounts for about 16% of the world's human population

​North America

​North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It can also be described as the northern subcontinent of a single continent, America.

​South America

​South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere. It can also be described as the southern subregion of a single continent called America.

​Antarctica

​Antarctica, the southernmost continent and site of the South Pole, is a virtually uninhabited, ice-covered landmass. Most cruises to the continent visit the Antarctic Peninsula, which stretches toward South America.

​Australia or Oceania

​Oceania is a geographic region that includes Australasia, Melanesia, Micronesia and Polynesia. Spanning the Eastern and Western Hemispheres, Oceania has a land area of 8,525,989 square kilometres and a population of over 41 million

​Europe

​Europe is a landmass variously recognised as part of Eurasia or a continent in its own right, located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere.
