Ch 7: Holt McDougal Earth Science Chapter 7 - Plate Tectonics

About This Chapter

The Plate Tectonics chapter of this Holt McDougal Earth Science Online Textbook Help Course helps students learn essential earth science lessons on 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 Holt McDougal 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 about:

  • Internal layers in the Earth
  • Scientific methods for studying internal structure of the earth
  • Theoretical explanations for Pangaea
  • Wegener's continental drift theory
  • Proof of continental drift
  • Plate tectonic theories
  • Convergent, divergent and transform boundaries of plates
  • Causes of tectonic plate movement
  • Types and causes of rock deformation
  • Causes and types of geological folds
  • Geological faults
  • Processes of mountain building

Earth's Internal Layers: Crust, Mantle & Core

1. Earth's Internal Layers: Crust, Mantle & Core

Earth is made up of several different layers, each with unique properties. In this video lesson, you will identify each layer of Earth and how it relates to Earth as a whole.

How Scientists Study Earth's Interior Structure

2. How Scientists Study Earth's Interior Structure

We can't see what Earth's interior is made of, but scientists are able to study it in other ways. In this video lesson, you will learn how seismic activity helps us understand and describe the inner layers of the earth.

What is Pangaea? - Theory & Definition

3. 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

4. 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

5. 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

6. 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.

Plate Boundaries: Convergent, Divergent, and Transform Boundaries

7. 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.

Causes of Tectonic Plate Movement

8. 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.

Rock Deformation: Causes and Types

9. 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.

Geological Folds: Definition, Causes & Types

10. 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.

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.

The Processes of Mountain Building

12. 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.
