A continent is one of several very large landmasses of the world. Generally identified by convention rather than any strict criteria, up to seven regions are commonly regarded as continents: Asia, Africa, North America, South America, Antarctica, Europe, and Australia.
Depending on the convention and model, some continents may be consolidated or subdivided: For example, Eurasia is most often subdivided into Asia and Europe, while North America and South America are sometimes recognised as one American continent, The Americas.
As for me, I would like to apply yet another convention and divide contents of this site into the regions / continents Americas, Asia, Europe and Scandinavia. Hope, you don't mind as it does fit the presentation of all the pics taken by me while traveling the world much better.
It's all 'under construction' anyway: In about one galactic year (roughly 225 million earth years) from now, all the continents on Earth may fuse - yet again - into a supercontinent. Three potential arrangements of this configuration have been dubbed Amasia, Novopangaea and Pangaea Ultima.
Europe is a continent located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west and the Mediterranean Sea to the south. It comprises the westernmost part of Eurasia.
