Take a look at the map of the world.0:12
Can you find Africa and South America on it?0:14
Don't you think you can easily put them together like a puzzle and make them one continent?0:18
Well, about a hundred years ago, a German scientist, Alfred Wegener, was sure that South America and Africa used to be one continent.0:24
The coasts of the South Atlantic Ocean on the territory of Brazil are very much like the eastern coastlines of Africa.0:36
Then there are also facts that many plants and animals used to be more or less the same in the prehistoric life of South America and Africa.0:44
That was why Wagener thought that these two continents used to be one great landmass.0:54
200 million years ago, he created a theory which he called the theory of the displacement of continents.1:00
According to this theory, the landmasses of the Earth were once one continuous continent.1:09
They used to be one great mass of land.1:16
Then, for some unknown reason, this landmass began to break up.1:19
South America separated from Africa and moved away.1:25
North America separated from Western Europe and moved to the West.1:30
That was how all the continents appeared.1:35
Did this really happen as Wagener says it did?1:39
But as you can see from the map, it is quite possible.1:45
And the further studies of prehistoric plant and animal life show that it is really possible.1:50
So perhaps Wegener was right.1:57
