Evidence of the Continental Drift

In class we had to do a puzzle with the Earths crust which is know as the continents. This helped us by: matching the continents together, like South America and Africa.
We also did a lab where we read a book. It said that there was a tropical fossil in Antarctica that Wegener found. So this tells us that at one point, Antarctica, South America, and Africa were once all together. In the book again it said that the mountain ranges in Africa and South America have similar mountains. Which tells us that South America and Africa were together.
