Rock Cycle is an interactive Web site where students can learn all about rocks and geology, the science of rocks. They will learn how rocks can be identified, how they are formed, and how they change over time. Students will identify the three major kinds of rocks and learn how to tell them apart. They will also discover how the different types of rocks are formed. Despite what students might assume, rocks actually change over time. Students will learn what kind of changes can happen to rocks, and about the processes that cause these changes. Putting all this knowledge together, students will understand that the rock cycle — a continuous pattern of change — helps explain what happens over and over again to the rocks in our earth.
