Ch 7: Earth's Formation & Structure

About This Chapter

Watch our video lessons to study the formation and structure of the Earth. This chapter covers how Earth developed and also takes you through the forces and factors that created this planet's structures.

Earth's Formation & Structure - Chapter Summary

In this chapter's video lessons, our experienced instructors guide you through the structure of Earth. You'll explore theories that explain how the different parts of our planet - including landforms, water and the atmosphere - developed. The lessons also teach you how scientists are able to study Earth's interior. Once you finish the videos, you should be able to respond to the following:

  • Discuss theories on how the Earth formed
  • Identify forces that shape the Earth's surface
  • Describe the Earth's internal layers
  • Explain how scientists study the interior structure of Earth
  • Define and describe the magnetosphere

We make studying entertaining and flexible with our lessons. The videos, which are usually about five minutes long, include simplified explanations, diagrams and engaging images that you can view on your mobile devices. The lessons also come with written transcripts that set off key terms and vocabulary in bold print. After you've studied, you can test your knowledge by taking the multiple-choice lesson quizzes.

Formation of the Earth: Theories

1. Formation of the Earth: Theories

In this lesson, the theory of how the planet Earth formed will be discussed. This includes looking at how it differentiated into three layers, how it formed its atmosphere, water, and land features, and how it continues to evolve today.

The Dynamic Earth: Internal & External Forces that Shape Earth's Surface

2. The Dynamic Earth: Internal & External Forces that Shape Earth's Surface

There are many geologic processes that shape the surface of the Earth. Not only do they build and destroy a variety of landscapes, but they also give us clues to the interior of the Earth and the forces that exist there.

Earth's Internal Layers: Crust, Mantle & Core

3. 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

4. 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.

Magnetosphere: Definition & Facts

5. Magnetosphere: Definition & Facts

In this lesson, you'll learn about how the northern lights are formed thanks to the magnetosphere and solar wind. Of course, you'll learn a lot more, including what the Van Allen belts, magnetopause, and magnetotail are.
