- 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 Earth's Spheres and Structures 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 Earth's Spheres and Structures chapter exam to be prepared.
- Get Extra Support: Ask our subject-matter experts any question about Earth's spheres or structures. 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 Earth's spheres and structures unit of a standard middle school earth science course. Topics covered include:
- How the Earth is shaped
- Weathering and deposition
- The four spheres of Earth
- Interactions of Earth's spheres
- Earth's internal layers
1. What is Earth Science?
Earth science is a field that includes geology, astronomy, meteorology, and oceanography. Scientists do research in these fields to discover past and future events. Learn about the dynamic field of earth science and how it affects our lives in this lesson.
2. How The Earth is Shaped: Earthquakes, Faults & Tsunamis
If you thought that the best way to describe the Earth's surface was round, think again! As this lesson shows, the world is much more like a soccer ball than you might imagine.
3. The Changing Earth: Volcanoes, Weathering & Deposition
While we may not see it every day, the world is always changing. In this lesson, with the help of an ill-informed tour guide, we will see how volcanoes, weathering, and deposition work to continually change the surface of our planet.
4. 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.
5. 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.
6. 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.
7. Lower Mantle: Definition, Composition & Facts
This lesson is on the lower mantle, an important part of the earth. Here, we'll cover what the lower mantle is and what it's made of. We'll also go over where you can find it and its importance in shaping our planet.
