Ch 9: OAE Earth & Space Science: Plate Tectonics

About This Chapter

In preparation for the OAE Earth and Space Science exam, complete the activities of this chapter to increase your knowledge about the major plates of the lithosphere, causes and evidence of tectonic plate movement and components of plate tectonic theory.

OAE Earth & Space Science: Plate Tectonics - Chapter Summary

This chapter has been assembled to help you prepare for questions on the Ohio Assessments for Educators (OAE) Earth and Space Science exam about the properties and theories of tectonic plates and tectonic plate movement. Watch the lesson videos taught by expert instructors to improve your understanding of the changes in Earth's surface, evidence supporting plate tectonic theory, Earthquakes and the rock cycle. After completing these lessons you should be better prepared for questions about:

  • The theories of plate tectonics and continental drift
  • Major plates of the lithosphere
  • Causes of tectonic plate movement
  • Types and components of plates boundaries
  • Evidence supporting plate tectonic theory and continental drift
  • Effects of tectonic plate movement
  • Rock deformation and the rock cycle

If at any time during this chapter you become confused about one of these topics be sure to ask our instructors of clarification so that you can master the information presented. After completing these lessons be sure to complete lesson quizzes to find out what topics you don't understand, then fortify your understanding of these topics by returning to the lessons with video tags or the lesson transcripts.

OAE Earth & Space Science: Plate Tectonics - Chapter Objectives

The OAE Earth and Space Science test is used in the state of Ohio to certify educators of geology, oceanography and astronomy. It is a computer-based certification exam with 150 multiple-choice questions. On testing day you will be asked to complete these questions in a three hours testing session. Be prepared for 25% of these questions to be about topics of geology including some on plate tectonics and the rock cycle. Use these lessons and quizzes to improve your understanding of these topics so that you will be prepared for related questions on test day.

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.

Major Plates of the Lithosphere: Earth's Tectonic Plates

2. 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

3. 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

4. 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.

Ocean Drilling as Evidence for Plate Tectonics

5. Ocean Drilling as Evidence for Plate Tectonics

The Deep Sea Drilling Project extracted samples of the ocean floor that provided evidence to support the hypothesis of seafloor spreading and the theory of plate tectonics. Learn how these samples provided proof.

Paleomagnetism and Hot Spots: Evidence for Plate Tectonics

6. Paleomagnetism and Hot Spots: Evidence for Plate Tectonics

Paleomagnetism is the study of past magnetic fields. Hot spots are fixed pockets of heat that well up to form volcanic features. Learn how paleomagnetism and the study of hot spots provide evidence that supports the theory of plate tectonics.

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.

Alfred Wegener's Theory of Continental Drift

8. 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

9. 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.

What is an Earthquake? - Definition and Components

10. What is an Earthquake? - Definition and Components

Earthquakes are well known for the damage and destruction they leave behind. But what is an earthquake? In this video lesson you will learn about what causes earthquakes and the various components involved in these powerful natural disasters.

Geological Faults: Definition, Causes & Types

11. Geological Faults: Definition, Causes & Types

In this video lesson, you will identify different faults and the types of stress that cause them. You will also see examples of the effects these faults have on the landscape.

Geological Folds: Definition, Causes & Types

12. Geological Folds: Definition, Causes & Types

Under the right conditions and over millions of years, rock can be deformed so that it is folded into a different shape. In this video lesson, you will identify different types of folds as well as what causes them to occur in rock.

The Processes of Mountain Building

13. The Processes of Mountain Building

In this video lesson, you will learn about the process of mountain building. You will identify different ways that mountains form, as well as the different types of mountains that result from this process.

Rock Deformation: Causes and Types

14. Rock Deformation: Causes and Types

In this video lesson, you will learn about how rock can be deformed from stress and the effect this has on the rock. You will identify different types of deformation based on the composition of the rock as well as external stress factors.

Rock Cycle: Igneous, Sedimentary, and Metamorphic Rocks

15. Rock Cycle: Igneous, Sedimentary, and Metamorphic Rocks

In this lesson, we will discuss the three main types of rocks and how they are formed. The lesson also gives an introduction into how matter locked in rocks can be cycled through the earth.
