Answer: Europe as the second smallest continent in the world.
Step-by-step explanation:
The western frontier of Europe defines the Atlantic Ocean. In this part of Europe borders with North and South America. The northern limit of Europe is the arctic ocean, which divides Europe from Canada and Alaska. The southern boundary of Europe is the Caucasus, which divides Europe and Asia.
Southeastern Europe and its border area in that part of the world is the Black Sea, separating Europe and Asia Minor. The eastern border is represented by the Urals and the Caspian Lake separating Europe and Kazakhstan.
