As shown on the History Channel, "How the Earth Was Made: Death Valley" explores the geologic history of Death Valley, tracing how plate tectonics, volcanism, erosion, climate, and water shaped one of North America’s most extreme landscapes. The video explains key Earth science concepts including limestone formation, stromatolite fossils, granite intrusions, faulting, crustal stretching, basin formation, rain shadow effects, evaporation, borax deposits, flash floods, and sliding rocks at Racetrack Playa. Using geologic evidence such as fossils, tilted rock layers, turtleback rocks, salt pans, and ancient shorelines, it shows how Death Valley changed from an ancient sea to a freshwater lake and then to a hot desert basin still sinking today. This documentary supports school curriculum topics in geology, weather, landforms, and scientific investigation. Part of the "How the Earth Was Made" series.
