About This Chapter

Gather additional facts about plate tectonics through this chapter's online video lessons. As you review the lesson topics and complete the quizzes, you can prepare to answer some of the questions on the TExMaT Master Science Teacher 8-12 examination.

TExMaT Master Science Teacher 8-12: Plate Tectonics - Chapter Summary

The engaging video lessons in this chapter focus on plate tectonics and related theories. While getting ready to take the TExMaT Master Science Teacher 8-12 examination, you can refresh your memory on the following:

  • Pangaea theory and plate tectonics
  • Alfred Wegener's theory and evidence of continental drift
  • Earth's tectonic plates as well as the origins of plate movement
  • Formation of plate boundaries
  • The significance of ocean drilling to sample the ocean floor
  • Paleomagnetism and sea floor spreading

Given the fact that you have probably already studied many of these plate tectonics topics, you might use these short video lessons as review tools that get you ready to answer questions on the TExMaT Master Science Teacher 8-12 examination. Educational in nature but also fun to watch, the videos are led by instructors who have extensive backgrounds in science. You'll be able to study at your pace and submit your questions on plate tectonics. Written transcripts accompany the video lessons. When you've watched a lesson, take the brief multiple-choice quiz that follows to test your understanding.

Plate Tectonics: A Unified Theory for Change of the Earth's Surface

1. Plate Tectonics: A Unified Theory for Change of the Earth's Surface

After many years of trying to solve the mystery of the moving continents, enough data and evidence was collected to develop a unifying theory of how the surface of the earth changes. It's called plate tectonics.

Alfred Wegener's Theory of Continental Drift

2. Alfred Wegener's Theory of Continental Drift

People used to think that Earth was static, and that it never changed. Gradually, a body of evidence was gathered that made no sense in this model. Alfred Wegener, Geologic Supersleuth, laid the groundwork for a whole new theory for the large-scale changing nature of the earth.

Major Plates of the Lithosphere: Earth's Tectonic Plates

3. Major Plates of the Lithosphere: Earth's Tectonic Plates

The outer shell of the earth, the lithosphere, is broken up into tectonic plates. The seven major plates are the African plate, Antarctic plate, Eurasian plate, Indo-Australian plate, North American plate, Pacific plate and South American plate.

Causes of Tectonic Plate Movement

4. Causes of Tectonic Plate Movement

In this lesson, we explore the causes of plate movement, including thermal convection, ridge push and slab pull. Students will learn how these processes complement each other and form a theory for tectonic plate movement.

Sea Floor Spreading and Polar Reversal

5. Sea Floor Spreading and Polar Reversal

Sea floor spreading is the process by which new oceanic crust is formed by the upwelling of magma through diverging tectonic plates. Learn about the relationship between sea floor spreading and polar reversals detected on the ocean floor.
