This 1935 Erpi Classroom Film looks at how rivers are formed and shape the environment around them. It starts with how small streams turn into large rivers through the water cycle. This is followed by how gullies, canyons, flood plains, and drainage areas are created. The film ends with the erosion that rivers cause through waterfalls and sediment deposits.
