Ch 34: Earth's Internal Structure & Processes

About This Chapter

Go over this chapter's text and video lessons to learn about the Earth's internal structure and processes. Learn about different facts about landforms, plate tectonics, layers of the Earth and more!

Earth's Internal Structure & Processes - Chapter Summary

If you would like to learn about the internal structure and processes of the Earth, go through these lessons that teach you essential facts from geology that will help you better understand the planet that we live on.

These lessons are a great way to learn about different phenomena found in or on the Earth itself, such as geologic folds and faults, as well as the scientific backgrounds on these topics, like evidence that supports the theory of plate tectonics. You can also learn how volcanoes are formed and see what causes an earthquake. Specific topics also covered in this chapter include:

  • The crust, mantle and core of the Earth
  • The Earth's shape and the effects of gravity, density and stress
  • Types of landforms
  • Geological maps
  • The Earth's magnetic field
  • Plate tectonics, paleomagnetism and continental drift
  • Types of faults and folds
  • Reasons for a volcanic eruption
  • Components and epicenter of an earthquake
  • Seismic waves

You can test your understanding of these topics by answering the questions found in the chapter's practice quizzes and final exam once you complete the lessons. If you would like further clarification on specific topics related to the structure and processes of Earth, you have the ability to message the lesson instructors. Make sure that you use your personal Dashboard to see how much progress you are making as you complete different lessons.

Earth's Internal Layers: Crust, Mantle & Core

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.

Shape of the Earth: Density, Stress & Gravity

2. Shape of the Earth: Density, Stress & Gravity

This lesson will seek to explain geodesy and the Earth's shape. In doing so, it will highlight the concepts of gravity, density, and stress, as well as the role they play in the field of geodesy.

Landform: Definition & Types

3. Landform: Definition & Types

Read about landforms and their major features. Learn the differences between formations like mountains and hills, valleys and canyons. (Hint: It has to do with their form.)

Geologic Maps: Topographic, Cross-Sectional & Structural

4. Geologic Maps: Topographic, Cross-Sectional & Structural

Geology is a very visual science, and the use of a variety of map types is common. This lesson will differentiate between three types of geologic maps: topographic, cross-sectional, and structural.

Earth's Magnetic Field: Formation, Changes & Impact

5. Earth's Magnetic Field: Formation, Changes & Impact

Earth has a magnetic field surrounding it. In this lesson, we will go through what creates it, how it changes, and what impact the change has on our planet.

Plate Tectonics: A Unified Theory for Change of the Earth's Surface

6. 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.

Evidence for the Mechanism of Continental Drift

7. Evidence for the Mechanism of Continental Drift

As scientists began to explore the ocean floor after World War II, they discovered many new clues to help them solve a mystery that had begun decades earlier - how the continents moved about on the surface of the earth.

Paleomagnetism and Hot Spots: Evidence for Plate Tectonics

8. Paleomagnetism and Hot Spots: Evidence for Plate Tectonics

Paleomagnetism is the study of past magnetic fields. Hot spots are fixed pockets of heat that well up to form volcanic features. Learn how paleomagnetism and the study of hot spots provide evidence that supports the theory of plate tectonics.

Geological Folds: Definition, Causes & Types

9. Geological Folds: Definition, Causes & Types

Under the right conditions and over millions of years, rock can be deformed so that it is folded into a different shape. In this video lesson, you will identify different types of folds as well as what causes them to occur in rock.

Geological Faults: Definition, Causes & Types

10. 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.

What is a Volcano? - Definition & Eruptions

11. What is a Volcano? - Definition & Eruptions

Volcanoes are vents that allow lava, rock fragments and gases to escape from layers beneath the earth's surface. Learn how volcanoes form both on land and underwater and why they erupt.

What is an Earthquake? - Definition and Components

12. 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.

The Causes of Earthquakes

13. The Causes of Earthquakes

In this video lesson you will learn what causes earthquakes and where they occur. You will also understand the theory of elastic rebound, and how this relates to movement of the earth's crust.

Seismic Wave: Definition, Types & Frequency

14. Seismic Wave: Definition, Types & Frequency

In this lesson, you will learn what seismic waves are, the various types of seismic waves, and their frequencies. You will learn about P-waves, S-waves, Rayleigh waves and Love waves. A short quiz will follow.

What is the Epicenter of an Earthquake? - Definition & Location

15. What is the Epicenter of an Earthquake? - Definition & Location

This lesson will explain what an epicenter is in the context of earthquakes, where it is located, and how that location is determined. A short quiz will follow.
