How does a river form?

Answer 1

Water will always try to flow to the lowest level. Therefore, if water is unable to continue its journey to the sea (lowest level) then lakes, marshes, etc. will naturally form in any hollow. Rivers are simply water on the move.

Answer 2

Rivers are channels of freshwater that pass through the land and get their start from the overflow of a larger body of water such as a lake. It can also form from runoff of heavy rains or snow melting from mountains. Rivers can start of small and get wider when different streams merge.

It is formed by erosion. Water flows through the land. It erodes the and forming a narrow channel. Water flows in these channels. When many of these channels meet they form a river.

They all start as run-off rain or snow-melt water! Lakes are incidental although a given river might be considered to start from a lake fed by a number of small tributaries.

Answer 3

A "river" is the path water takes to the sea, to a lake, or to another river closer to the sea. In North America, all water that does not evaporate eventually travels down one or more streams or rivers to the Atlantic Ocean, the Gulf of Mexico, the Pacific Ocean, the Arctic Ocean or Hudson's Bay. Over time, the water will wear a trench through the ground it travels over. It will cut a deeper, narrower trench through softer soil. It will cut a shallower, broader path over harder soil or rocks, and may form a lake.

"Lakes" are basins filled with water by streams or rivers. The basin may be the result of water flowing through an area for a long time, or it may have been "scooped out" by glacial movement.

If you look at the end of a downspout after a heavy rain, you may see these formations in miniature.

Answer 4

Streams (tribituaries) enter another stream making it larger, finally making it a river.

Answer 5

Erosion, the water in the stream gradually wears away at the edges causing them to collapse and disintergrate, imagine rubbing a piece of sandpaper against a brick to get the right idea.
