we all know all continents and countries used to be joined as one 'pangea'. well i also read that many scientists believe that in say '250 million years' they will go back to form the original pangea...or very similar. could this be what all the big earthquakes are about, the plates moving ever so closure together. just a thought but after 250 million years of types of earthquake we have been getting then it wouldnt be surprised if the continents do move back together.
