Where rivers come from
The vital waterways that transport water around continents begin as just a tiny trickle
Whether they gush dramatically down a rock face or subtly slip through the landscape, the transportation of water in rivers is essential to many life forms on Earth. Rivers are natural channels of water that carry surface freshwater to seas and lakes. As well as relocating the water to a larger body, they also distribute nutrients such as nitrogen and phosphorus around the planet and to oceans.
