• 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

Why did no one believe Wegener's ideas about continental drift? (Choose 2)

• He could not successfully explain HOW the continents moved

• He didn't have evidence that supported his ideas that the continents had once been connected

• They were biased against his ideas because he was German and a meteorologist

• He didn't use the right technology to gather data

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.

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.

Massive pieces of land that are part of the Earth's crust and upper mantle

• Tectonic plates

• Trenches

• Divergent boundary

• Continental shelves
