Continental Drift Activity

In this activity, you and a partner will explore the concepts of continental drift and plate tectonics. By accessing the provided website, you'll answer a series of questions about the Earth's crust composition, the nature of tectonic plates, and various geological phenomena. Your tasks include diagramming Earth's layers, discussing crust density, examining the age differences between continental and oceanic crusts, and understanding how plate movements lead to events such as earthquakes and mountain formation. Submit your findings as a group effort.

  1. Continental Drift Activity

  2. Continental Drift Activity • You and a partner will go to the following website to help answer a few questions: • http://www.enchantedlearning.com/subjects/astronomy/planets/earth/Continents.shtml • You and your partner only need to hand in one piece of paper with both of your names on it.

  3. Questions – Page 1 of 4 • What is the Earth’s crust made of? • What are the plates made of, why do they change in size over long periods of time, and how thick are they? • Draw a diagram of Earth’s layers. • How does the temperature of the Earth effect the size of continents? • What are Earth’s 7 largest plates? • What are 7 smaller plates?

  4. Questions – Page 2 of 4 • What natural phenomena does plate tectonics explain? • Which type of crust is most dense? • What is the major component of continental crust, and oceanic crust? • Why is the average age of continental crust much older than oceanic crust? • What is the asthenosphere and where is it found?

  5. Questions – Page 3 of 4 • What are the three types of plate movement? • How does seafloor spreading create new oceanic crust, and at what type of boundary is it found? • What happens when an oceanic plate and a continental plate collide? Why? • How are mountains created? • How do transform plate boundaries cause earthquakes?

  6. Questions – Page 4 of 4 • According to Wegener what does the crust drift on? • Once Pangaea broke up, what two continents formed first? • What is a Mesosaurus and how did it help prove the theory of continental drift?
