What body of water flows from a higher elevation to a lower elevation?
What body of water flows from a higher elevation to a lower elevation?
What is a river? A river forms from water moving from a higher elevation to a lower elevation, all due to gravity. When rain falls on the land, it either seeps into the ground or becomes runoff, which flows downhill into rivers and lakes, on its journey towards the seas.
What causes water to flow from higher elevations to lower elevations or move downward into the ground?
Ultimately, gravity is the driving force, as water moves from mountainous regions to sea level. Some of this water moves over the surface and some moves through the ground as groundwater. As this water flows it does the work of both erosion and deposition.
What happens to a river’s flow as it reaches lower elevations?
Water evaporates from the ocean, lakes and rivers and condenses into clouds. For some water this is in the form of surface flow or runoff in creeks and rivers. In both cases, the water will continue to flow and pick up minerals, nutrients and pollution, until it reaches a body of water that is at low elevation.
Is it safe to play in creeks?

Is it safe to drink water from a creek?
Never drink water from a natural source that you haven’t purified, even if the water looks clean. Water in a stream, river or lake may look clean, but it can still be filled with bacteria, viruses, and parasites that can result in waterborne diseases, such as cryptosporidiosis or giardiasis.
What determines a river from a creek?
It can be a small stream, an inlet from the sea or a narrow channel that connects islands. It is often a shallow branch of a river and is much smaller than a river. While rivers can have several branches or tributaries, a creek does not. Rivers flow in channels and have branches or tributaries while creeks do not.
