The theory that says Earth's continents once made up an ancient super continent, and have been drifting apart ever since due to convection currents, is called the theory of:

• Plate Tectonic Theory

• Plate Drift Theory

• Continental Drift Theory

• Seafloor spreading theory

The Appalachian Mountain range in North America is similar in age and rock composition to mountain ranges in Britain and Norway. Similarly, the mountain range that runs east to west in South Africa matches a mountain range that is now separate across the ocean. This evidence supports:

• Continental Drift Theory

• Seafloor Spreading Theory

• Plate Tectonic Theory

• Magnetic Reversal Theory

Originally, the Continental Drift theory was not well received by other scientists. Why?

• The scientist presenting the data was not well received by other scientists.

• There was no data showing the continents ever moved

• There was no competing theory at the time that was more believable

• The scientists did not know the force responsible for moving the continents

Which of the following supports the theory of seafloor spreading?

• Magnetic reversals recorded in rocks

• Continuous mountain chains

• Correlation of rock layers

• Crustal slab pull

How does fossil evidence support Wegener's hypothesis of continental drift?

• Fossils are found in areas where the present-day climate could not have supported the organisms that made the fossils.

• Similar fossils are found on land-dwelling dinosaurs are found on continents separated by oceans

• Similar fossils are found along continental margins that appear to join together

• All of the above

The theory of continental drift named a key part of this idea Pangaea. What is Pangaea?

• One of the ancient animals that helped Wegener prove that fossils from different continents originally came from the same location

• The hot spot which gave rise to the Hawaiian Islands, among others

• The underwater ocean range in the middle of the ocean

• supercontinent that existed in Earth's distant past
