Earth Processes, Third Edition

Earth Processes begins and ends with two important, related geological theories: continental drift and plate tectonics. In the activities, students examine the evidence supporting these explanations of Earth's dynamic landforms. Students construct a layered Earth replica that demonstrates our planet's structure. Next, students replicate the formation of the three types of rock and discover how heating, cooling, compression, and weathering create a perpetual rock cycle. Then, they explore, map, and measure the forces that result in earthquakes, volcanic eruptions, and mountain-building. They model the explosive events that make plate margins, especially the Pacific Rim's Ring of Fire, the most volatile area on Earth. (14 Activities)
