About 250 million years ago, during the time of the supercontinent Pangaea, Antarctica was not in the South Pole where it is today. Instead, it was located closer to the equator.Because of its position near the equator, Antarctica had a warm and tropical climate, with forests, rivers, and many animals living there. Over millions of years, the movement of tectonic plates slowly pushed Antarctica southward until it reached its present location at the South Pole, where the climate is now extremely cold and icy.
