What two continents were the most obvious to likely have been together?
South America and Africa
How did the continents drift?
By plate tectonics, but it get more detailed soon.
Why do the continents move further from each other every year?
Because new crust is made regularly pushing the old crust away.

What are tectonic plates?
Pieces of Earth's crust and uppermost mantle.
When did Pangaea start to form?
300 million years ago.
What type of scientist was Alfred Wegener?
Meteorologist.
Why was the theory of continental drift not accept when it was introduced by A.W.?
Because he did not have a mechanism to explain how the continents move.
