The Rock Cycle--Introduction
This simplified model shows the variety of ways in which Earth's rocks evolve into other types of rocks. For example, an igneous rock may weather away and its particles eventually combine to become a sedimentary rock. The same igneous rock may remain buried deep beneath the Earth's surface, where heat and pressure might convert it into a metamorphic rock. The same igneous rock, if it is buried even deeper, may actually melt to become magma-which may eventually recool and solidify to form a new igneous rock. There is no prescribed sequence to the rock cycle. Any rock's evolution may be changed at any time by a change in the geological conditions around it.

    • Sedimentary Rocks
    • Metamorphic Rocks
    • Igneous Rocks
  2. You will also learn about the various processes that are part of the rock cycle including:
    • Metamorphism

    • Cooling and solidification

About this site
This site is a resource for both teachers and students. For teachers, it can be used to supplement their class. It also provides many activities that they can incorporate into their classrooms to give students hands on experience. This can also help generate interest in the subject.

The Rock Cycle Web Site is also a great place for students. By using the map above, students can get an idea of how the rock cycle works. If they have any questions about a certain rock or process all that they need to do is click on it and they will be taken to a page containing information on that topic. One of the most beneficial aspects of the site is that it allows students to test their knowledge through our on-line quizzes.

How to use this site
 You can move throughout this site by by using the navigation bars at the top. You can also begin by selecting one of the rocks or processes on the image above.
