How a river is formed?

A river begins as a source at the top of a mountain. This source could be: a spring, glacier, rain or even collected snow. This source travels down the hill/mountain(because of gravity ), after that the source enters  a waterfall. The waterfall then pushes the source to the main channel. There can be parts of the main channel where a tributary ( smaller river) can  join the main channel. This place is called a confluence. Where a river enters the mouth (ocean) is called an estuary. There can sometimes be delta which block part of the water from flowing in. On both sides of the river is a floodplain. When the river floods the floodplain floods. The river can cut through it forms a meander and leaves an oxbow lake.
