The continents are in constant motion: Tectonic plates crash together and break apart, creating new crust while old crust is pulled below the surface. The process shrinks and widens oceans, uplifts mountain ranges, and rearranges landmasses. In about 250 million years a new supercontinent, Pangaea Proxima, will form.

Only a vestige of the Atlantic Ocean remains
as landmasses are joined together into a new
supercontinent. New high mountains mark
the sites of massive collisions.
