About This Chapter
Earth: Layers, Forces & Magnetic Field - Chapter Summary
In this chapter, you'll review a series of video lessons that cover the layers, forces and magnetic field of the planet Earth. As you work through the chapter at your own pace, you'll refresh your knowledge of the Earth's crust, mantle and core, as well as the effects of tectonic plate movement, erosion and weathering. You can also review interesting facts about the Ring of Fire and the forces that shape the Earth's surface. By the end of the chapter, you should be able to:
- Compare the internal layers of the Earth
- Understand what causes the movement of tectonic plates
- Locate the Ring of Fire
- Recognize the internal and external forces that influence the shape of the Earth's surface
- Explain how landforms are affected by deposition and erosion
- Define the concept of weathering
- Describe the characteristics of the Earth's magnetic field
Review these lessons whenever you have free time in your schedule, and be sure to take the accompanying self-assessment quizzes to retain key concepts. Your dashboard will keep track of your progress. If you want to study offline, you can print out the accompanying lesson transcripts; otherwise, you can review the lesson material on any device that has an Internet connection.
1. 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.
2. 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.
3. 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.
4. What Is the Ring of Fire? - Definition, Facts & Location
The Ring of Fire has produced the world's most destructive and active volcanoes, not to mention most of the world's earthquakes. Read on to find out just what the Ring of Fire is and the volcanoes it has created throughout the planet's history.
5. Effect of Erosion and Deposition on Landforms
Landforms are constantly being broken down and reformed by the processes of weathering, erosion, and deposition. In this lesson, we explore chemical and physical weathering and how the face of the earth gets changed.
6. Weathering: Definition & Explanation
Discover how rocks and minerals are broken down by chemical and mechanical forms of weathering. Learn about some of the many geological formations created by weathering, from large caves to beautiful arches made of rock.
7. Earth's Magnetic Field: Definition & Characteristics
This lesson will discuss Earth's magnetic field, why our planet has one, what causes it, and how Earth's magnetic field is essential for the survival of human beings.
