This video is divided into four major sections: PHYSICAL WEATHERING: Discover how plants, animals, ice, water, and air all contribute to the disintegration of rocks. CHEMICAL WEATHERING: Oxidation and carbonic acid are discussed. Highlights include a journey into wondrous limestone caverns to see the effects of chemical weathering. EROSION: Examples such as Yosemite Valley, Bryce Canyon, and the Grand Canyon help students realize the long-term effects of erosion and weathering. SOIL FORMATION: Describes the three basic ingredients necessary to form soil: rock particles, organic matter, and a community of living plant and animal organisms. Â
