This class rocks! We will begin by looking at the material that is belched out of different types of volcanos like Kilauea in Hawaii, Mt. St. Helens in Washington, Mt. Pinatubo in the Philippines, and Yellowstone. We'll contrast igneous rocks from those volcanos with the sedimentary rocks around Cincinnati and metamorphic rocks in the Appalachian Mountains. We'll also determine why Cincinnati's hillsides are on a downward slide and many more rocky topics.
