Which direction did India drift away from Pangaea?
Around 120 million years ago what is now India broke off and started slowly migrating north at about 5 centimeters per year. Then about 80 million years ago the continent suddenly sped up racing north at about 15 centimeters per year — about twice as fast as the fastest modern tectonic drift.
How did Pangea drift away?
Scientists believe that Pangea broke apart for the same reason that the plates are moving today. The movement is caused by the convection currents that roll over in the upper zone of the mantle. This movement in the mantle causes the plates to move slowly across the surface of the Earth.

How South America and Africa fit together?
