A continent is a large geographical region defined by the continental shelves and the cultures on the continent. In the modern day, there are seven continents. However, there have been more continents throughout history. Vaalbara was the first supercontinent. Europe is the newest continent. Geologists have predicted that certain continents will appear, these being Pangaea Proxima, Novopangaea, Aurica, and Amasia.
