Ch 6: Overview of Geomorphology

About This Chapter

In these lessons you will review the four spheres of Earth, the inner layers of the Earth, the forces that have shaped the earth and the geological time scale of these changes. Use our study aids to master these and related topics.

Overview of Geomorphology - Chapter Summary

Watch the lessons of this chapter to review the characteristics of the different spheres of the Earth, inner layers of the Earth and how they interact to shape the form of the Earth, geomorphology. Each lesson video is taught by a professional instructor who will help you improve your understanding of geomorphology by explaining:

  • Characteristics of the geosphere, hydrosphere, biosphere and atmosphere
  • Interactions between the Earth's spheres
  • Characteristics of the crust, mantle and core
  • Relationship between the density, gravity and shape of the Earth
  • Internal and external forces that have shaped the Earth's surface
  • Major eons, eras, periods and epochs of geomorphology

For and additional review of these topics, read the lesson transcripts. These written overviews of the lessons will help you reinforce your retention of the information and key vocabulary. After each lesson, test your understanding of the material by taking the lesson's quiz. Then use the video tags to return to and study the parts of the lesson that discuss the topics you missed.

The Four Spheres of Earth: Geosphere, Hydrosphere, Biosphere, and Atmosphere

1. The Four Spheres of Earth: Geosphere, Hydrosphere, Biosphere, and Atmosphere

Earth is made up of four distinct yet connect spheres. In this video lesson, you will learn about where each sphere is found on Earth, as well as some features commonly found in each.

Interactions of Earth's Spheres: Purpose and Examples

2. Interactions of Earth's Spheres: Purpose and Examples

The four spheres of Earth drive all of its processes and support life on our unique planet. In this video lesson, you will see examples of how Earth's spheres interact with each other to form an overall complex and connected system.

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.

Shape of the Earth: Density, Stress & Gravity

4. 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.

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

5. 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.

Geologic Time Scale: Major Eons, Eras, Periods and Epochs

6. Geologic Time Scale: Major Eons, Eras, Periods and Epochs

The geologic time scale is an essential tool for understanding the history of Earth and the evolution of life. In this lesson, explore the principal eons, eras, periods, and epochs that help us track major events in geologic history.
