Ch 21: The Earth's Internal Structure: Physical Science Help & Review

About This Chapter

The Internal Structure of the Earth chapter of this High School Physical Science Help and Review course is the simplest way to master the internal layers of the Earth. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure students learn the essentials of the internal structure of the Earth.

Who's it for?

Anyone who needs help learning or mastering high school physical science material will benefit from taking this course. There is no faster or easier way to learn high school physical science. Among those who would benefit are:

  • Students who have fallen behind in understanding the features of Earth's spheres, the composition of Earth's internal components or working with physical science and the internal structure of the Earth
  • Students who struggle with learning disabilities or learning differences, including autism and ADHD
  • Students who prefer multiple ways of learning science (visual or auditory)
  • Students who have missed class time and need to catch up
  • Students who need an efficient way to learn about physical science and the internal structure of the Earth
  • Students who struggle to understand their teachers
  • Students who attend schools without extra science learning resources

How it works:

  • Find videos in our course that cover what you need to learn or review.
  • Press play and watch the video lesson.
  • Refer to the video transcripts to reinforce your learning.
  • Test your understanding of each lesson with short quizzes.
  • Verify you're ready by completing the Internal Structure of the Earth chapter exam.

Why it works:

  • Study Efficiently: Skip what you know, review what you don't.
  • Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
  • Be Ready on Test Day: Use the Internal Structure of the Earth chapter exam to be prepared.
  • Get Extra Support: Ask our subject-matter experts any internal structure of the Earth question. They're here to help!
  • Study With Flexibility: Watch videos on any web-ready device.

Students will review:

This chapter helps students review the concepts in an internal structure of the Earth unit of a standard high school physical science course. Topics covered include:

  • The geosphere, hydrosphere, biosphere and atmosphere
  • Interactions of Earth's spheres
  • Earth's crust, mantle and core
  • Scientific study of Earth's interior structure

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.

How Scientists Study Earth's Interior Structure

4. 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.

Upper Mantle: Definition, Facts, Temperature & Composition

5. Upper Mantle: Definition, Facts, Temperature & Composition

The mantle is just one layer of the Earth, but it's a big one. The upper mantle is dense yet fluid in places and is responsible for volcanoes and the movement of tectonic plates.
