Ch 27: GED Science - Earth's Spheres and Internal Structure: Tutoring Solution

About This Chapter

The Earth's Spheres and Internal Structure chapter of this GED Science Tutoring Solution is a flexible and affordable path to learning about Earth's spheres and internal structure. These simple and fun video lessons are each about five minutes long and they teach all of the features of Earth's spheres and internal structure required in a typical GED science course.

How it works:

  • Begin your assignment or other GED science work.
  • Identify the Earth's spheres and internal structure concepts that you're stuck on.
  • Find fun videos on the topics you need to understand.
  • Press play, watch and learn!
  • Complete the quizzes to test your understanding.
  • As needed, submit a question to one of our instructors for personalized support.

Who's it for?

This chapter of our GED science tutoring solution will benefit any student who is trying to learn Earth's spheres and internal structure and earn better grades. This resource can help students including those who:

  • Struggle with understanding geosphere, hydrosphere, internal layers, forces that shape Earth's surface or any other Earth's spheres and internal structure topic
  • Have limited time for studying
  • Want a cost effective way to supplement their science learning
  • Prefer learning science visually
  • Find themselves failing or close to failing their Earth's spheres and internal structure unit
  • Cope with ADD or ADHD
  • Want to get ahead in GED science
  • Don't have access to their science teacher outside of class

Why it works:

  • Engaging Tutors: We make learning about Earth's spheres and internal structure simple and fun.
  • Cost Efficient: For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.
  • Consistent High Quality: Unlike a live GED science tutor, these video lessons are thoroughly reviewed.
  • Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn about Earth's spheres and internal structure on the go!
  • Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.

Learning Objectives

  • Discuss the internal and external forces that shape the surface of Earth.
  • List Earth's four spheres.
  • Provide examples of interactions between Earth's spheres.
  • Describe the internal composition of Earth.
  • Explain how scientists study the interior structure of Earth.

14 Lessons in Chapter 27: GED Science - Earth's Spheres and Internal Structure: Tutoring Solution
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.

Asthenosphere: Definition, Temperature & Density

6. Asthenosphere: Definition, Temperature & Density

The asthenosphere is a layer of the inner earth where the crust begins to melt into the mantle. This lesson will discuss the important properties of the asthenosphere.

Core of the Earth: Facts, Composition, Layers & Temperature

7. Core of the Earth: Facts, Composition, Layers & Temperature

This lesson will discuss the layers of the Earth, focusing particularly on the Earth's core, including its chemical composition, temperature, and how the core creates the Earth's magnetic field. A short quiz will follow.

Earth's Mantle: Definition & Facts

8. Earth's Mantle: Definition & Facts

What do we really know about that big, thick orange layer we see in so many cross-sectional diagrams of the Earth's interior? The mantle is a strange place, but it affects us all the time.

Inner Core of the Earth: Definition, Composition & Facts

9. Inner Core of the Earth: Definition, Composition & Facts

The inner core is located at the center of the Earth and is composed of nickel and iron. Most of what we know about the inner core is through studying seismic waves. This lesson will cover the facts about the inner core.

Lava Flow: Definition & Types

10. Lava Flow: Definition & Types

This lesson defines lava and explores the different chemical distinctions of lava. By the end of this lesson, you should be able to name the different types of lava and some of its distinctive morphologies.

Oceanic Crust: Definition, Composition & Facts

11. Oceanic Crust: Definition, Composition & Facts

A thin layer of rock separates the Earth's oceans from the hot mantle beneath them. In this lesson, you'll read about the composition and life cycle of this oceanic crust, and take a quiz to test your understanding.

The Continental Crust: Definition, Formation & Composition

12. The Continental Crust: Definition, Formation & Composition

This lesson will explain what the continental crust is, describe its composition and properties, and discuss the history of how the continental crust was formed.

The Layers of the Earth: Facts, Composition & Temperature

13. The Layers of the Earth: Facts, Composition & Temperature

This lesson will discuss the layers that make up the inside of the Earth chemically, including their composition, temperatures, and the states. A short quiz will follow.

The Lithosphere: Definition & Composition

14. The Lithosphere: Definition & Composition

The lithosphere is where we live. It is also the source of many geologic events that affect us. In this lesson, you will learn more about this important part of our planet.
