This is the complete Geology series- Volumes 1, 2 and 3.

A look at the Earth as a dynamic system in action. Earth’s formation, shape, size, motions, internal structure and magnetic field. Geological history and time scales. The changing geosphere. Plate tectonics and continental drift—plus earthquakes and volcanoes!

A look at Earth’s raw materials and how they are cycled and recycled. Minerals and crystal structure. Atomic bonding. The three main rock groups: igneous, metamorphic and sedimentary. Rock formations and the rock cycle. Renewable and non-renewable resources.

Earth’s surface is always changing. This CD looks at erosion in all its forms—from wind, water and ice to plate tectonics. Folds, faults and impact structures. How soil is formed and how it varies with climate and latitude. How small and large forces act over time to change the Earth’s face.
