Before Pangea: The Supercontinents

Video Description

Long ago, the Earth's seven continents were assembled in a giant, sprawling supercontinent known as Pangea. You may've heard of it, but what is often less talked about is what came before Pangea. Our planet's current continental chunks have been smashing together and separating for over four billion years, and there have been more than a few "supercontinents" during that time. Those lost lands take the stage in this video, as we wind the clock back to the age of the supercontinents before Pangea. This one has been in the pipeline for many months. It is slightly different to the usual astronomy content but I hope you will all enjoy it just the same.
