Earth's+Tectonic+Plates

=﻿__ Discussion Questions __
 * Is Earth's surface stable and stationary now? Was it ever in the past? Do you think it will be stable in the future?
 * Do you think that the way continents fit together is convincing evidence for the theory of plate tectonics? Why or why not?
 * What was the supercontinent called that once contained nearly all of the continental crust? Research what the name means.
 * Which ocean is growing in size? Which is shrinking? Explain why this is occurring.
 * How does the theory of plate tectonics help us explain natural phenomena such as earthquakes and mountains, which geologists had difficulty accounting for prior to the development of the theory?

Fill out the CEC (Claim, Evidence, Conclusion) worksheet.



What was Wegener's claim about continental drift? What evidence was put forward? Did everyone agree? What is your conclusion?

Discussion Questions
 * **Look at the interactive flash animation of [|tectonic plates]. Add the earthquakes view, then the volcano's then the tectonic plates. What do you notice?

[|Mountain maker, earth shaker!] Use the interactive animation to explore plate boundaries. Fill out the attached grid explaining what happens at each plate boundary. Draw a diagram of each type of boundary.
