No, gravity does not directly cause rivers to flow. Rivers flow due to the force of gravity pulling the water downstream. The elevation gradient along the river channel allows the water to move from higher to lower elevations, creating the flow of the river.

Yes - water flows from a higher elevation to a lower elevation. That's why a lot of rivers flow from South to North
The direction that a river flows is called the flow or the drainages. Water generally flows downhill or from a higher elevation to a lower one.
Gravity is what causes a river to flow from higher to lower elevation. A river travels at a faster speed the higher the elevation and will typically cause greater erosion.
The Niagara River Flows North because land elevation to the south is higher, causing the flow to go north. Land elevation drops about 325 feet from the mouth of the Niagara River at Lake Erie to the bottom of Niagara Falls and continues to drop to Lake Ontario.
The Netherlands (Low-Lands) are North of the Alps. This is where the river starts. The elevation grade from Switzerland to the river's mouth in the Netherlands declines.

The Red River is a major North American river located in North Dakota. The reason that the Red River flows north is due to the fact that the location of the river is 200 feet higher in elevation than the water in which it feeds into. This causes the water to the lowest point of elevation which actually sits to the north of the river.
in relation to the flow dynamics of the water against standing water(resistance) and the widening if the river in relation to flow (expanding area in relation to pressure) it would be easy to see that the flow can diminish. what factors need to be taken into account is changes in the elevation of the flow ( decreasing elevation would obviously increase the flow and elevated areas would widen the river and create lakes) this can be seen by rapids and pooling in the river. so velocity would be a variable but the gallon per minute flow would be more of a constant please let me know if this helps you hockeylvn@hotmail.com
