About This Chapter
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.
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.
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.
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.
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.
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.
