Ch 27: Overview of Plate Tectonics

About This Chapter

Review and study plate tectonics at your convenience using this professionally designed chapter. Whether you're finishing an assignment or getting ready for a test, the lessons and self-assessment quizzes provided here make it easy to understand these subjects.

Overview of Plate Tectonics - Chapter Summary

In this interesting chapter, our professional instructors outline plate tectonics for you. Lessons cover related topics such as compiled evidence of this concept, plate boundaries and plates as they're related to earthquakes and tsunamis. Once you complete this chapter, you should be able to:

  • Outline plate tectonics as the unified theory for change on Earth's surface
  • Identify the evidence for plate tectonics
  • Explain how ocean drilling can be used as evidence for plate tectonics
  • Discuss the causes of tectonic plate movement
  • Detail how plate tectonics are affected by density and buoyancy
  • Explore convergent, transform and divergent plate boundaries
  • Describe how plate movement affects volcanic eruptions, tsunamis and earthquakes
  • Identify the factors that determine the impact of an earthquake

You'll find the resources included in this chapter easy to use, mobile-friendly and accessible 24 hours a day. If at any point as you work through the lessons you have questions, feel free to submit them through the Dashboard for one of our instructors to address. We've included helpful self-assessment tools here as well, including lesson quizzes and a comprehensive chapter test.

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.

Evidence of Plate Tectonics

2. Evidence of Plate Tectonics

After reading this lesson, you'll learn what things scientists observe in the natural world that lead them to believe that plate tectonics is the way our continents were formed.

Ocean Drilling as Evidence for Plate Tectonics

3. 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.

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.

How Density & Buoyancy Affect Plate Tectonics

5. How Density & Buoyancy Affect Plate Tectonics

In this lesson we'll be exploring the forces behind plate tectonics. We'll look at different types of plates and their properties, including density and buoyancy, and how it affects the results of plate interactions.

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.

How Plate Movement Affects Earthquakes, Tsunamis & Volcanic Eruptions

7. How Plate Movement Affects Earthquakes, Tsunamis & Volcanic Eruptions

Earthquakes, volcanoes, and tsunamis are all dangerous natural disasters, but they also have something else in common - tectonic plate movement. In this lesson, you'll see how these seemingly different events actually come from similar geological beginnings.

Factors That Determine the Impact of an Earthquake

8. Factors That Determine the Impact of an Earthquake

Ever wonder why some earthquakes are literally earth-shattering, while others go unnoticed? This lesson will highlight the contributing factors that determine whether earthquakes register at all or are catastrophic occurrences.
