Bill Nye The Science Guy 4 7 -1 -1 251059 0.0 0.0 0 Water is massive; rivers are powerful. As rivers flow downhill, they wear away rock and soil to form canyons or winding curves in the land, called meanders. Sometimes rivers fill and overflow their banks.

Rivers and streams support most of the ecosystems on land. 26 http://image.tmdb.org/t/p/original/7VasFnXlXP0XYZVRnxR6k5sCa52.jpg 1996-01-12 1996-01-12 false Rabbit Ears Productions Public Broadcasting Service KCTS Television James McKenna Bill Nye Michael Gross Kit Boss Erren Gottlieb Ian G.
