In this activity, students will make observations then construct a "sample" model representation of the Earth's layers. They will compare and contrast the movement and material in each layer explaining the location and what it contains.

This interactive activity adapted from A Science Odyssey Web site helps you visualize different types of plate tectonic activity and shows the impact this activity has on Earth's surface.

From ABC News in Science, Will Dunham's article covers research connected to the discovery of a chunk of Earth's crust found in Greenland which possibly dates over 3.8 billion years.

This textbook excerpt explains the concept of isostasy and the relationship of Earth's crust to the mantle beneath it. This process is compared to the effects of glaciation and describes the effect an ice sheet has on the crust, and the...

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....

The purpose of this lesson is to introduce students to the basic elements of our Earth's crust: rocks, soils and minerals. They learn how we categorize rocks, soils and minerals and how they are literally the foundation for our...

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...
