A continent is a large geographical region defined by the continental shelves and the cultures on the continent.[1] In the modern day, there are seven continents. However, there have been more continents throughout history. Vaalbara was the first supercontinent.[2] Europe is the newest continent.[3] Geologists have predicted that certain continents will appear, these being Pangaea Proxima, Novopangaea, Aurica, and Amasia.
