According to the continental drift hypothesis, the presence of similar fossils in South America and Africa supports which scientific idea?

• Animals easily and frequently travel from Africa to South America.

• Species of animals probably traveled between continents on natural rafts (such as trees destroyed in tsunamis).

• Land bridges once existed that connected the continents.

• South America and Africa were once connected together.

The Appalachian Mountains in the U.S. match up with a similar mountain ranges in northern Europe. How does this support Wegener's theory of Continental Drift?

• The mountains were formed after tectonic plates had moved away from each other

• The similarities provide evidence North America & Europe were connected when the mountains formed.

• Similar rock samples were found on the ocean floor and at the two mountain ranges indicating that they both formed around the same time.

• This evidence does not support the theory of continental drift.
