Weathering and Erosion - 1985

Educational video from the mid-1980s covering the geological topics of weathering and erosion.
From the VHS box: "This program explores how the surface of the earth is in constant struggle with the elements. Wind, running water, gravity, and temperature changes break down rock formations and carry away material to build up deltas, beaches, geosynclines, and dunes."
