ELI5: Why is Europe considered to be a continent and not just a peninsular of Asia?
gpt
Continents are largely a cultural concept; they have never been very consistently defined by geography alone. After all, North and South America are attached, and Africa is attached to Asia as well.

Europe is traditionally considered a separate continent because it has been culturally, economically and politically distinct from Asia for most of its history, and this arises from geographic borders like the Ural Mountains and climate of central Russia.
