Find out about the interior structure of the Earth and the role of seismic waves as they move through Earth's layers. The research details both compositional layers as well as mechanical layers.

Visit an active volcano site to find out the connection between the movement of the Earth's plates and the processes deep within the Earth's interior. [58:23]

What covers less than 10% of the Earth's surface, yet is a vital natural resource for terrestrial life? What filters ground water and supports most of our food production, not to mention the production of building materials and paper?...

This teacher website provides a comprehensive lesson unit on the structure of Earth's atmosphere and how it sustains and impacts life on Earth and its ecosystems. Includes labeled diagrams, student worksheets, a slideshow, flashcards,...

Here's a project that involves a different kind of sandbox than the ones you usually think of. This one has a moving wall inside, acting like a piston, to compress the sand. You can make layers using two different colors of sand, and...

Describes each of the five layers of the atmosphere from the troposphere, which is closest to the Earth, up to the outermost one, the exosphere.

Students build a model to learn about the cycle of erosion and deposition by water and wind which deposits layer upon layer of rock, soil, and organic material to the surface.

Simulate core sampling with this lesson. Students will see layers of Earth with this activity.

In this activity, students use popcorn to simulate the process scientists use to date layers in an ice core.

This lesson will allow the students to understand the cause and effects of plates interactions. The students will learn that plate boundaries function as a release for much of the Earth's potential energy. The students will be able to...

Apple provides a description of the USAtlas Geology app, developed by the USGS. The app provides 46 layers of vector information available at The National Atlas of the United States Website.
