From Wikipedia, the free encyclopedia.
Eurasia refers to the combined land mass of Europe and Asia. Eurasia is alternatively considered to be a continent, or a supercontinent composed of the continents of Europe and Asia.
Due to the cultural differences between Asia and Europe, the historical tradition is to consider them separate continents. (This is controversial, as many historians perceive much of South and West Asia as historically closer to Europe than to East Asia). The earth sciences, with a more precise definition of continent, more frequently consider Eurasia to be a continent in and of itself.
Eurasia can be geographically defined by subtracting Africa from the
great land mass of Africa-Eurasia. The dividing line between Europe and Asia is traditionally placed along the Ural Mountains.
Eurasia was also a fictional country comprising approximately the same land area in the novel Nineteen Eighty-Four.
