How do rivers keep flowing?
How do rivers keep flowing? The energy of flowing river water comes from the force of gravity, which pulls the water downward. The steeper the slope of a river, the faster the river moves and the more energy it has. The movement of water in a river is called a current. The current is usually strongest near the river's source.
Will rivers ever dry up?
Climate change and in some cases, pollution, are the reasons that rivers are running dry all over the world.
