6 Lessons in Chapter 27: GED Science - Earth's Spheres and Internal Structure: Help and Review
The Dynamic Earth: Internal & External Forces that Shape Earth's Surface

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.

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

2. 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

3. 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

4. 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.

How Scientists Study Earth's Interior Structure

5. 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.

Mesosphere: Definition, Facts, Temperature & Characteristics

6. Mesosphere: Definition, Facts, Temperature & Characteristics

The atmosphere is made up of many layers, and in the middle is a mysterious layer known as the mesosphere. In this lesson, you will learn the characteristics of the mesosphere, its location within the atmosphere, and how scientists study it.
