Continental Drift + Plate Tectonics

This is a picture of glacier scars found in Africa.  What are these evidence for?

• Africa has always been near the equator
• Africa was once in an area of the Earth that had a very cold climate
• The continents have not moved
• sea floor spreading

What does the theory of continental drift state?

• The continents were once joined in a super-continent and have moved over time
• Continents are stationary and do not move
• The Earth is broken into lithospheric plates that move due to convection currents
• none of the above

According to Wegener's hypothesis of continental drift,

• Earth's surface is made up of seven major landmasses

• the continents DO NOT move

• Earth is slowly cooling and shrinking

• the continents were once joined together in a single landmass, and these plates will continue to move.

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.

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.

Which of the following best describes Wegener's continental drift ideas?

• Hypothesis: There was data to support the idea but more information was needed to build it into a scientific theory.

• Theory: It was an early idea of Wegener's but it didn't yet have any evidence to support it.

• Theory: It was a well supported idea that explained many things. No additional information was needed (it just needed time for people to accept it).

• Hypothesis: It was an educated guess that Wegener made based on maps, but he hadn't yet collected experimental data.
