Ch 2: Understanding Plate Tectonics: Help and Review

About This Chapter

The Understanding Plate Tectonics chapter of this Middle School Earth Science: Help & Review course is the simplest way to master plate tectonics. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure you learn the essentials of plate tectonics.

Who's It For?

Anyone who needs help learning or mastering plate tectonics material will benefit from the lessons in this chapter. There is no faster or easier way to learn about plate tectonics. Among those who would benefit are:

  • Students who have fallen behind in understanding plate tectonics
  • Students who struggle with learning disabilities or learning differences, including autism and ADHD
  • Students who prefer multiple ways of learning science (visual or auditory)
  • Students who have missed class time and need to catch up
  • Students who need an efficient way to learn about plate tectonics
  • Students who struggle to understand their teachers
  • Students who attend schools without extra science learning resources

How It Works:

  • Find videos in our course that cover what you need to learn or review.
  • Press play and watch the video lesson.
  • Refer to the video transcripts to reinforce your learning.
  • Test your understanding of each lesson with short quizzes.
  • Verify you're ready by completing the plate tectonics chapter exam.

Why It Works:

  • Study Efficiently: Skip what you know, review what you don't.
  • Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
  • Be Ready on Test Day: Use the plate tectonics chapter exam to be prepared.
  • Get Extra Support: Ask our subject-matter experts any question about plate tectonics. They're here to help!
  • Study With Flexibility: Watch videos on any web-ready device.

Students Will Review:

This chapter helps students review the concepts in a plate tectonics unit of a standard middle school earth science course. Topics covered include:

  • Pangaea
  • Plate tectonics
  • Wegener's theory of continental drift
  • What makes tectonic plates move
  • Types of plate boundaries
  • Evidence of plate tectonics and continental drift

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.

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

2. 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.

Alfred Wegener's Theory of Continental Drift

3. 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

4. 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.

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.

Ocean Drilling as Evidence for Plate Tectonics

7. 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.
