Eurasia

n. continents of Europe and Asia considered together

Eurasia is an immense landmass covering about 53,990,000 km² (or about 10.6%) of the Earth's surface. Often reckoned as a single continent, Eurasia comprises the traditional continents of Europe and Asia, concepts which date back to classical antiquity and the borders for which are somewhat arbitrary. Eurasia, in turn, is part of the yet larger landmass of Africa-Eurasia, whereby Asia is joined to Africa at the Isthmus of Suez.
