Rivers and Their Impact on Nature

The video explores how rivers shape the land, provide resources, and support ecosystems. It explains river formation from rain, snow, and springs, and discusses erosion, river features like meanders and waterfalls, and the impact of glaciers. The video highlights Blue Heart Springs, river currents, rapids, and the Teton Dam failure. It concludes with rivers as habitats and resources for humans, and directs viewers to Science Trek for more information.
