THE GROUND IS MOVING

CONTINENTAL DRIFT
Until 1800 it was thought that the continents any time in the history of Earth were on their today’s positions but then Alexander von Humboldt saw that the S.American eastern coast was fit perfectly with the western coast of Africa,in 1800 he chartographed them to get stuck together.So we know that the continents are moving,the tectonic plates were formed some 3 billion years ago.Then they move and change the face of the planet every day,for example the Atlantic ocean is opening just about our fingernails grow.Australia is moving north faster than every other land mass.450 million years ago a supercontinent Gondwana was formed by S.America,Africa,S.Europe,Australia and Antarctica,the other continents are small land masses near the equator.377 million years ago Antarctica,Africa and S.America are formed still Gondwana the other continents are islands all over the equator.250 million years ago all the continents are stuck together in the biggest continent that ever existed,Pangea.200 million years ago Pangea started to break off, N.America spitted from the supercontinent and started to move on.90 million years B.C. all the continents [except Europe and Asia]are alone in the bigger than today oceans.30 million years ago the continent are just a few miles from their today’s sits.Finally today are as we see them but how the world will like in 5,100 or 200 million years from now?The answer will write in some of the next articles.
