Eurasia

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. 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.
