What Makes a River Flow?

Rivers flow because water moves from high places to low places, like a ball rolling down a hill. When it rains or snow melts, the water runs downhill and creates a river. Sometimes gravity pulls it all the way to the ocean!

Examples

  1. Rain falling on a mountain makes the water run down into a stream.
  2. Snow melting in spring turns a frozen valley into a flowing river.
  3. Water from a lake flows out through a narrow channel into a river.
