Ch 14: ScienceFusion The Dynamic Earth Unit 4.2: Plate Tectonics

About This Chapter

The Plate Tectonics chapter of this ScienceFusion The Dynamic Earth Companion Course helps students learn the essential lessons associated with plate tectonics. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Plate Tectonics textbook chapter.

How It Works:

  • Identify the lessons in the ScienceFusion Plate Tectonics chapter with which you need help.
  • Find the corresponding video lessons with this companion course chapter.
  • Watch fun videos that cover the plate tectonics topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • The theory of continental drift
  • Evidence of continental drift
  • The definition for plate tectonics
  • Reasons for plate movements
  • Different types of plate boundaries

Alfred Wegener's Theory of Continental Drift

1. 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.

Evidence for the Mechanism of Continental Drift

2. Evidence for the Mechanism of Continental Drift

As scientists began to explore the ocean floor after World War II, they discovered many new clues to help them solve a mystery that had begun decades earlier - how the continents moved about on the surface of the earth.

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

3. 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.

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.

Plate Boundaries: Convergent, Divergent, and Transform Boundaries

5. Plate Boundaries: Convergent, Divergent, and Transform Boundaries

In the theory of plate tectonics, the earth's crust is broken into plates that move around relative to each other. As a result of this movement, three types of plate boundaries are formed: divergent, convergent, and transform boundaries.
