The rocks and soil that make up Earth's surface are constantly being affected by a variety of forces, ranging from heat and frost to water and wind. In Weathering and Erosion, students will discover the natural forces that cause weathering, erosion and deposition, and see the many effects that these processes have on Earth's surface. Students will examine natural structures around the world and see how weathering and erosion have affected them, while discovering ways in which people have become better prepared to battle these forces through conservation. In addition, a fun, hands-on experiment demonstrates how running water erodes different types of soil. Part of the Earth Science in Action DVD Series. A Teacher's Guide is included and available online. 23 minutes. Grades 5 to 8.
