This is an in-depth activity where students create a rock layer formation using different colors of playdough and investigate the types of folds and rock formations that might occur. They take core samples through anticlines and...

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...

A lengthy scholarly article that discusses the geologic time scale, its history of development, age-dating events that occurred in different eras, and how absolute and relative dating are used to assess the ages of the Earth and Moon....

This site was created by two geoscientists. They explain the Principles of Geology. These are general rules, or laws, that are used to determine how rocks were created and how they changed through time. They are also used to determine...

Understand the characteristics and features of Earth's core from this detailed article. Includes high-quality illustrations, a downloadable poster, a video, and links to other resources.

In this amazing interactive tutorial, you'll learn about minerals - the building blocks or rocks and the Earth. We'll talk about what makes something a mineral, and how differences in these minerals let us organize them into different...
