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.
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.
