Scientists think the continents once formed a large, single landmass that broke apart, and then the continents slowly drifted to their present locations. What is the name given to this hypothesis?

• slap pull
• continental drift

Mountain ranges and fossils provided evidence that the continents were

• Separated by a larger ocean.
• once joined together as one land mass.

The fact that South America, Africa, India, Australia and Antarctica had evidence of Glossopteris, a tropical fern, provides evidence that

• they had similar animals on them because they were together.
