In-depth resource for identifying rocks. Includes an interactive rock identification key to help you figure out the name of your rock.

Explore the different types of rocks on our Earth as you watch a one-hour video, accompanied by learning goals, details on sedimentary rocks, fossils, and supercontinents, and more.

Click on the shelves in this virtual exhibition to learn about the many rocks and minerals that we use in our everyday lives.

Describe and sort rocks by their physical properties.

Rocks cover the earth's surface, including what is below or near human-made structures. With rocks everywhere, breaking rocks can be hazardous and potentially disastrous to people. Students are introduced to three types of material...

Explains what granite it, and has an alphabetical listing of different types of granite, with pictures and details.

Describes different landform types and their features. includes many good quality photographs.

Use crayons to model the rock cycle in this fun activity! You will make colorful sedimentary, metamorphic, and igneous "rocks" from crayon shavings.

Presents photographs of examples of clastic, chemical, and organic sedimentary rocks, with short descriptions underneath each rock image. Each rock name is also linked to its own dedicated page with a great deal of additional information...

Learn about the different types of igneous rocks and how they are classified.

[Free Registration/Login may be required to access all resource tools.] Covers metamorphic rocks, which form from previous rocks exposed to heat and/or pressure.

Students complete field and museum observations and work with local geologists to collect information on various types of rocks. Each student then creates a trading card with an original illustration of the rock on the front and the...

A rock chart the describes the texture, appearance, characteristics, type, and where each is formed.

A lab with good info on metamorphic rock definitions, factors, grades, types, and composition. These are lecture notes and overheads from a geology class, and useful for review.

This site explores the classification of igneous rocks. Content addresses classification based on color and texture, mineral composition, and chemical composition.

Explains the difference between intrusive and extrusive igneous rocks and provides pictures and descriptions of common igneous rock types in each category.

[Free Registration/Login may be required to access all resource tools.] Presents the classifications of igneous rocks based on silica content.

To experience the three types of material stress related to rocks - tensional, compressional and shear - students break bars of soap using only their hands. They apply force created by the muscles in their own hands to put pressure on...

In this interactive tutorial, you will learn about the types of weathering and erosion that rocks and landforms undergo. This will lead to a discussion of soil and the types of soil. Lastly, you will learn about mass movements of soil,...

Slope failure is the downslope movement of rock debris and soil in response to gravitational stresses. Three major types of mass wasting are classified by the type of downslope movement. The types of movement, falls, slides, and flows...

In this interactive tutorial you will learn how pressure creates stress and strain on rocks. Learn how different types of strain are produced by different plate tectonic settings, and explore the different types of mountain ranges and...

Students continue their pyramid building journey, acting as engineers to determine the appropriate wedge tool to best extract rock from a quarry and cut into pyramid blocks. Using sample materials (wax, soap, clay, foam) representing...

Describes the different types of mechanical weathering and how each of them breaks down rocks.

Sedimentary rock forms in layers that are deposited one after the other over long periods of time. Oftentimes, sedimentary rock contains fossils and other debris that are deposited within the layers. Use this experiment to investigate...
