About this image:
Africa's unique shape is the geological key to understanding how it became its own continent. The coastlines of Angola and Brazil fit together like puzzle pieces because, before there was an Atlantic Ocean, Africa and South America were united into one giant continent called Gondwana, that has since rifted apart into separate continents with an ocean in between.
