Like any body of water on land, rivers start with a simple drop of rain. That raindrop might fall into an already existing pond or lake, or it could seep through the ground and come up elsewhere through a spring. A river begins as a trickle that flows downhill. As it flows further, a river becomes wider and deeper. Kids will enjoy tracing the journey of rain from a stream all the way to the sea.
