Plants and animals are usually organized by their family tree (origin) and by their physical and genetic characteristics. This activity helps to demonstrate to students that geologists do the same with rocks, which are usually organized by their origin and by their physical and chemical characteristics. To have a better understanding of nature and as one of the initial steps of scientific understanding, ... Full description.

These resources on rock deformation are designed to help educators meet the new national science standards. The Rock Deformation Gallery displays illustrations from the Hall of Planet Earth, which has two informative overviews: Deformed Rocks; and Deforming Rocks in the Laboratory: Deformed Marble Cylinders. Also available is Deformed Conglomerate in the Hall of Planet Earth, which has three annotated ... Full description.

This comic strip is part of OLogy, where students can collect virtual trading cards and create projects with them. In this interactive comic strip, they learn about the geologic origins of four common objects: the sand in a drinking glass; the zinc, copper, nickel, and other metals in coins; the bauxite in a sheet of aluminum foil; and the oil in a plastic ball.

This atlas provides over 400 full colour photomicrographs of the major ore-forming mineral associations and opaque minerals in non-mineralized rocks. It describes typical examples of each mineral from many classical localities throughout the world. For each association there is a listing of the major (and important minor) primary ore minerals, alteration products and gangue, typical textures, a brief ... Full description.

The 3-D visualizations of molecules and minerals at this site utilize a plug-in viewer, which allows them to be interactively zoomed and rotated so they can be viewed from all angles, much as with a real molecule. They can also be programmed with highlighting features that allow identification of specific atoms, structural sub-components, and mineralogical planes. The visualizations are incorporated ...

This introduction to the rock cycle features an introduction to the three major rock types (igneous, sedimentary, metamorphic) and a simplified diagram of the rock cycle. Links provide access to more detailed information, featuring examples, descriptions, and photographs of each type. Igneous rocks are described on the basis of method of formation and mineral composition. Sedimentary rocks are classified ... Full description.
