How are rivers formed short answer?
Rivers are part of the hydrological cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, springs, and the release of stored water in natural ice and snowpacks (e.g., from glaciers).
Where do rivers originate?
Stream and river waters originate through contribution from various sources. The changes in isotopic composition of a river along its length allow one to quantify inputs from groundwater and tributaries.
How long does a river have to be?
Usually. There is no rule about length , volume of flow, width, peak flow or whether it flows all tear or is intermittent. There is no river police that decide these things. I live near the Sheep River and for most of the year it is only 6–8 inches deep, and 20 or so feet wide.
Where do rivers start and finish?
The headwater can come from rainfall or snowmelt in mountains, but it can also bubble up from groundwater or form at the edge of a lake or large pond. The other end of a river is called its mouth, where water empties into a larger body of water, such as a lake or ocean.
What are the two oceans that never mix?
The Indian Ocean and the Pacific Ocean meet in the Gulf of Alaska, but we can say that these two oceans do not even meet together. This is because its water is never mixed into each other.
What happens when two rivers meet?
A confluence occurs when two or more flowing bodies of water join together to form a single channel. Confluences occur where a tributary joins a larger river, where two rivers join to create a third or, where two separated channels of a river, having formed an island, rejoin downstream.
Why do the 2 Oceans not mix?
It’s not two oceans meeting, its glacial melt water meeting the off shore waters of gulf of Alaska. The reason for this strange phenomenon is due to the difference of water density, temperature and salinity of the glacial melt water and off shore waters of gulf of Alaska, making it difficult to mix.
