It's one thing to look into the past and guess at how this process moved
the continents to where they are today, and another thing to look at the way
the continents are still moving today and guess at where they might be going.
But that's exactly what at least one scientist, Christopher Scotese at the
University of Texas at Arlington, attempted to try and do.
Scotese has created an animation (shown in the video at the top of the
page) that predicts where Earth's continents might end up over the course of
the next 250 million years, and it turns out they might be on their way to
forming another supercontinent, reports the BBC.

The Continental Shuffle
Over two hundred fifty million years ago, India, Africa, Australia, and South America were all one continent called Pangea. Over the next several million years, this giant southern continent proceeded to break up, forming the continents we know today. Pangea essentially turned inside out, the edges of the old continent becoming the collision zones of new continents. Africa, South America, and Antarctica began to fragment.
What ultimately formed Mt. Everest, about 60 million years ago, was the rapid movement of India northward toward the continent of EuroAsia; Click here for a present-day map of the Indian subcontinent. India charged across the equator at rates of up to 15 cm/year, in the process closing an ocean named Tethys that had separated fragments of Pangea. This ocean is entirely gone today, although the sedimentary rocks that settled on its ocean floor and the volcanoes that fringed its edges remain to tell the tale of its existence.
