Effects of Plate Tectonics - Chapter Summary

This chapter helps you recall important aspects of plate tectonics. Instructors present each lesson in a fun and engaging manner. By the end of the chapter, you will have reviewed:

  • Names of the seven major plates on Earth
  • Divergent, convergent and transform plate boundaries
  • How continents move on Earth
  • Relationship between sea floor spread and polar reversals
  • Volcanoes on land and in water and reasons they erupt
  • Causes of earthquakes
  • Types of seismic waves, including P-wave, S-waves, Rayleigh waves and Love waves

Every one of these energetic and convenient video lessons features a short quiz. These quizzes ask questions about the topics covered in the lessons. You'll get immediate results from the quizzes, so you'll know what your strengths and weaknesses are. We also include a chapter test that goes over all of the lessons found in this chapter. This test is a comprehensive way to test your knowledge before moving on.

Major Plates of the Lithosphere: Earth's Tectonic Plates

1. 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.

Plate Boundaries: Convergent, Divergent, and Transform Boundaries

2. 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.

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.

Sea Floor Spreading and Polar Reversal

4. 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.

What is a Volcano? - Definition & Eruptions

5. What is a Volcano? - Definition & Eruptions

Volcanoes are vents that allow lava, rock fragments and gases to escape from layers beneath the earth's surface. Learn how volcanoes form both on land and underwater and why they erupt.

What is an Earthquake? - Definition and Components

6. 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.

Seismic Wave: Definition, Types & Frequency

7. Seismic Wave: Definition, Types & Frequency

In this lesson, you will learn what seismic waves are, the various types of seismic waves, and their frequencies. You will learn about P-waves, S-waves, Rayleigh waves and Love waves. A short quiz will follow.
