Description: Examines various agents of weathering, erosion, and deposition to show how these processes act together to change the earth's surface. Views materials in a deserted town being worn away by physical and chemical weathering and moved by erosion. Shows examples of natural landforms, including terraces, petrified caprock, sandstone formations, dikes, sand dunes, and sea coasts, which are eroded and rebuilt by wind, rain, temperature changes, running water, gravity, and glaciers., Explains the basic principles of weathering and erosion and describes the vital functions that both perform in modifying the Earth's surface.

Complete Record: Examines various agents of weathering, erosion, and deposition to show how these processes act together to change the earth's surface. Views materials in a deserted town being worn away by physical and chemical weathering and moved by erosion. Shows examples of natural landforms, including terraces, petrified caprock, sandstone formations, dikes, sand dunes, and sea coasts, which are eroded and rebuilt by wind, rain, temperature changes, running water, gravity, and glaciers., Outstanding photography documents the effects of physicial and chemical weathering on man-made structures and rock. Among erosional phenomena explored: the effects of running water (rain, rivers, hot springs); how glaciers have changed the deserts; how ocean waves and currents create beaches and shape shorelines; now gravity causes erosion through landslides and mass wasting., , Explains the basic principles of weathering and erosion and describes the vital functions that both perform in modifying the Earth's surface.NOTE: Two (or more) records have been merged together to create this data.
