As part of the General Chemistry Virtual Textbook, this site examines a variety of topics related to the Earth. This page looks at the Earth and its lithosphere, the chemical composition of the Earth, the structure of the Earth, and more.

Scholars explore the Earth science topic of the Earth's basic structure. The tutorial consists of definitions and pictures about the Earth's crust.

Project Mohole was "the earth sciences' answer to the space program," a project to gain information about the Earth by drilling a hole through the Earth's crust to the Mohorovicic Discontinuity (Moho). This website gives a history of the...

An infograph showing the chemicals that are present in Earth's crust.

What makes the Earth unique? What are the different parts of the Earth? What is the chemical make-up of the Earth? Get the answers to these questions and more on this site from the Australian Museum Online.

Take a look at the Earth from the inside out. This site shows the different layers of the earth with an explanation of the rocks and materials in each layer. Includes a quiz on the structure of Earth.

In this interactive tutorial you will learn about earthquakes and seismic waves. Learn about why and how these form and also discuss the hazards - direct and indirect - posed by earthquakes. You will then learn how our knowledge of...

This site provides a detailed discussion of the Earth's interior. Facts about the crust, mantle, and core are given along with diagrams of each. Also presents a table that lists the thickness and types of rock found in each part of the...

As an overview of the online exhibit on earthquakes, this site discusses the various sections inside the Earth. The crust, the mantle, and the core are each individually discussed.

This is a website to learn not only about the inner and outer core, but also about the crust and the mantle of the interior of the earth.

Create a model to help learn the layers and structures within the Earth. Identify characteristics of each layer of the Earth.

The Earth has been in a state of continual change since its formation. The major part of this change, involving volcanism and tectonics, has been driven by heat produced from the decay of radioactive elements within the Earth. The other...

Matching game on the earths core and crust. Students test their knowledge and learn what is below the earth's surface.

In this activity, students gain an understanding of the layers of the Earth by designing and building a clay model.

The Franklin Institute has provided a demonstration that theorizes how the earth's crust was formed. This is a lesson plan that needs only a few materials.

Earth Really Rocks is a teaching unit for Grades K-3. It approaches the study of rocks from an energy perspective, looking at how gas and oil are formed underground, as well as at sedimentary rocks and the structure of the Earth's crust....

This resource describes how seismic waves have helped us to understand the composition of the Earth's interior. It discusses seismic discontinuities, including the Mohorovicic Discontinuity or Moho, and what we have learned about the...

This lesson will help learners visualize the Earth's crust (lithosphere), mantle, and core. The students will work in groups to research and design a model of the Earth's layers. Some of the types of models include: computer, fruits such...

An easy-to-understand explanation of what plate tectonics is. Contains information about the inner parts of the Earth, the difference between the three types of plates, and numerous maps and illustrations.

Students use the Integrated Ocean Drilling Program as an example to help them find ways of checking science news stories for accuracy. They are given a science news story and instructed to investigate the accuracy of the claims made in...

Labeled diagram of a section of the Earth's crust.
