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.

An in-depth look at how isostasy works and the processes taking place during glaciation and the melting of glaciers. Looks at gravity and the effects of density differences within the crust and mantle, and at Earth's magnetic field and...

Journey into the past while reading this comprehensive overview of the Hadean Eon that covers topics such as the formation of the earth, its surface and atmosphere, fossil evidence, erosion and plate tectonics.

An in-depth look at the structure and composition of Earth's mantle, with lots of visuals. Covers lithosphere, Mohorovicic discontinuity, asthenosphere, transition zone, lower mantle, the d double-prime region, mantle convection, mantle...

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.

This site from PBS provides a description of the mechanisms behind the plate movements, types of movements, and the resulting earthquakes, faults, and images and animations of several of the topics presented.

Instructional module focusing on plate tectonics. Discussion includes plates, plate boundaries, and driving forces. Site also includes an interactive practice quiz and links relating to the topic.
