What Makes a River Flow Faster Than Another?

Rivers flow at different speeds because of how steep they are and what's in their way. Imagine a river like a slide, the steeper the slide, the faster you go! If there are rocks or plants blocking the way, it slows down. Rivers with fewer obstacles and more slope zoom along like race cars.
