About This Chapter
Structure & Internal Dynamics of the Earth - Chapter Summary
Our chapter on the structure and internal dynamics of the Earth is a handy way to review these topics at your own pace. You'll find video lessons here that cover subjects such as the internal layers of the Earth and the ways that scientists study Earth's interior structure. After completing this chapter, you should be ready to:
- Discuss plate tectonics and the theory associated with it
- Outline the causes of tectonic plate movement
- Identify the different kinds of plate boundaries
- Detail types of volcanoes and their characteristics
- Explain the formation of volcanic landforms
- Define an earthquake and its components
- Describe the causes and types of geological faults
- Provide the equation for and examples of isostasy
This helpful chapter is designed by expert instructors to outline these topics in a user-friendly format so you can easily understand them. If you'd rather not watch an entire video, use the video tabs feature to skip ahead to the part you'd like to see. Our printable lesson transcripts also make handy offline study guides if you'd like to review this information this 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. 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.
3. Plate Tectonics: A Unified Theory for Change of the Earth's Surface
After many years of trying to solve the mystery of the moving continents, enough data and evidence was collected to develop a unifying theory of how the surface of the earth changes. It's called plate tectonics.
4. 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.
5. 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.
6. Types of Volcanoes: Shield, Cinder Cones & Composite Cones
The earth ejects lava, rock fragments, hot vapor and gases during volcanic eruptions. Volcanoes vary based on size, shape, composition and eruptive style. Learn about the different types of volcanoes, such as shield, cinder cone and composite cone.
7. Volcanic Landforms: Types & Formation
Volcanic eruptions pull materials up from deep within the earth to form various volcanic landforms, such as lava domes, lava plateaus, fissure eruptions, craters and calderas. Learn about these volcanic landforms and how they are created.
8. 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.
9. Geological Faults: Definition, Causes & Types
In this video lesson, you will identify different faults and the types of stress that cause them. You will also see examples of the effects these faults have on the landscape.
10. Isostasy: Definition, Equation & Examples
In this lesson, we will discuss the principles of isostasy and how it affects our planet. The lesson will define isostasy, provide the equations used to calculate isostatic adjustments, and discuss some of the causes seen today.
