River water flows downhill due to gravity, and riverbanks keep the river contained (most of the time). Some rivers meander, too, due to the way rivers erode the land. The older a river is, the more it meanders.
Gravity, rivers flow downhill
The rivers were used for fishing, transportation, baths, and drinking water. Also for trading.

Melt. Move
They can erode mountains.
Although rivers don't actually, physically move themselves, but the water in them does. And its false.
True
Glaciers are large masses of ice that move very slowly, while rivers are bodies of flowing water that move faster. Glaciers are formed by the accumulation of snow over time, while rivers are formed by precipitation and runoff.
Rivers are positioned on hills, or uneven land. The rivers run downhill, so the water goes in that direction.
Piranha are freshwater fish. They don't move in the ocean. Their natural habitat is the rivers of South America.
