‘MinuteEarth’ Explains How Rivers Develop Curves

MinuteEarth (previously) has a new video explaining how rivers develop curves. Given a long enough time, even the smallest of factors can have a major effect on the flow of a river.

All it takes to turn a straight river stream into a bendy one is a little disturbance and a lot of time, and in nature, there’s plenty of both.

Music for the video was created by New York City-based folk artist Nathan Shroeder.
