A huge landmass, called Pangea, covered about a third of our planet. But about 175 million years ago, the Earth broke apart into continents, and formed the world we know today. ... If Pangea existed today, in theory, you could drive from California to England, since they'd both be part of the same landmass.
pangea took million of years to separate. Years by Years the continents move. for example The two continents are moving away from each other at the rate of about 2.5 centimeters (1 inch) per year. And there movent is due to the activity beneath the earths crust. The plates are moved by currents in the magma at the very surface of the earths mantle , which then in turn cause things like earthquakes and volcanic eruptions.
