Ch 47: CEOE Middle Level Science: Plate Tectonics

About This Chapter

Watch short video lessons in this chapter to get reacquainted with plate tectonics as you study for the CEOE Middle Level Science assessment. Lesson quizzes and a chapter exam can gauge your comprehension of the materials.

CEOE Middle Level Science: Plate Tectonics - Chapter Summary

This chapter can serve as a mini study guide with information you can use to prepare for plate tectonics questions on the CEOE Middle Level Science assessment. By exploring the lessons, you will be ready for the following on the test:

  • Defining and sharing the theory of Pangaea
  • Explaining Alfred Wegener's theory of continental drift
  • Providing evidence for the mechanism of continental drift
  • Describing major plates of the lithosphere
  • Identifying causes of tectonic plate movement
  • Discussing various types of plate boundaries
  • Sharing details about sea floor spreading and polar reversal

You can access a wide variety of resources in this chapter, all designed to enhance your preparations for the assessment. In addition to watching engaging videos, you can review full transcripts with helpful vocabulary words, and submit your questions about lesson topics to our experts.

What is Pangaea? - Theory & Definition

1. What is Pangaea? - Theory & Definition

The continents you know have existed for a long time, but not in their current locations. In fact, over 200 million years ago Pangaea broke apart by plate tectonic movement to form the continents we see today.

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.

Evidence for the Mechanism of Continental Drift

3. 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.

Major Plates of the Lithosphere: Earth's Tectonic Plates

4. 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

5. 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

6. 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.

Sea Floor Spreading and Polar Reversal

7. 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.
