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.
