Along time ago, Africa was not far from
South America. In fact, 300 million years ago all the land on earth was only
one big continental, called ‘Pangaea’.
Very
slowly, pangaea separated into two parts, and the future continents began to
move towards their places. But until 160 million years ago South America,
Africa, India, Australia, and Antarctica were still only one huge land mass
(‘Gondwannaland’). North America, Europe and Asia together made the other super
continent (‘Laurasia’)
Seas started to spread between the new
contonent. This was a slow process: Africa and South America only finished
separating 91 million years ago.
Some
strange results of land mass movements:
There is a diamond deposit that starts in
Africa, stops on the west coast, and begin again in South America.
Mountains in Norway, Scotland, Greenland
and the North-east US all belong to the
same mountain chain.
