“Europe and Asia, while often considered two separate continents, both lie on the same landmass or tectonic plate, the Eurasian supercontinent. The historic and geographic story of the Eurasian boundary is intriguing.“

Seth Dixon‘s insight:

While most continental borders follow some physical geographic definition, the border between Europe and Asia is purely cultural and a remant of classical regional differentiation.  Some argue that Europe isn’t a separate continent from Asia, and while they are not wrong, the concept of Europe is deep and pervasive in how we think about the world.
