Rocks That Form On The Earth's Surface (1964)

The film explores the processes of weathering and sedimentation that shape the Earth's surface. It explains how rocks break down into mud and sand through natural elements, which are then carried downstream by rivers. Sediments settle in layers as they reach calmer waters, such as reservoirs and oceans. Over time, pressure and cementation transform these sediments into sedimentary rocks like sandstone and limestone. The film also discusses how various natural processes, including the remains of marine life and plant materials, contribute to the formation of sedimentary rocks and their layered structure.
