Pangaea begins to break up. Pangaea (sometimes spelled Pangea), the most recent of a series of supercontinents on Earth, formed about 270 million years ago and broke apart about 200 million years ago. At this time most of the dry land on Earth was joined into one huge landmass that covered nearly a third of the planet's surface.
A new Pangaea could form within the next 50 million years when Africa and Australia merge with Europe and Asia! This assembly and subsequent break-up of Earth's landmasses is known as the supercontinent or Wegenerian cycle.hat's what scientists believe. They think that, about 270 million years ago, almost all of the land on Earth was part of one supercontinent. Today, scientists refer to that former supercontinent as Pangaea, which comes from a Greek word that means âall the Earth.. Pangaea covered about one-third of Earth's surface.
