About This Chapter
The Interior of the Earth - Chapter Summary
In this chapter, you'll study the interior of the Earth. Our lessons outline the internal layers of the Earth, including the crust, core and mantle. After completing this chapter, you should be able to meet the following objectives:
- Identify the layers, composition and temperature of the earth's crust
- Explain how the continental crust was formed
- Give facts about the oceanic crust
- Outline the velocity of p-waves
- Provide an example of an s-wave
These helpful learning tools are designed by professional instructors to help facilitate an enjoyable and interesting study experience. Each lesson is mobile friendly and accessible 24 hours a day. If you'd rather not watch an entire video, use the video tabs feature to skip ahead or go back to any section. Our instructors are available to answer your questions if you need assistance along the way.
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.
2. The Earth's Crust: Facts, Layers, Temperature & Composition
The Earth's crust is just a thin layer surrounding our world. Although it is the only part of the Earth any of us see, it makes up just one percent of the planet's total volume.
3. The Continental Crust: Definition, Formation & Composition
This lesson will explain what the continental crust is, describe its composition and properties, and discuss the history of how the continental crust was formed.
4. Oceanic Crust: Definition, Composition & Facts
A thin layer of rock separates the Earth's oceans from the hot mantle beneath them. In this lesson, you'll read about the composition and life cycle of this oceanic crust, and take a quiz to test your understanding.
5. P-Waves: Definition & Velocity
Primary (P) waves are compressional seismic waves that occur during an earthquake. This lesson will cover the properties of these waves and how they have helped us understand the inner workings of the earth.
6. S-Waves: Definition & Examples
S-waves are seismic waves produced by the energy released during an earthquake. S-waves can cause intense damage to structures and are important in determining the location of the epicenter. This lesson will cover the facts about S-waves.
