Tributaries contribute to the river in the early stage. Where a river forms a Delta the smaller rivers which branch out are Distributaries.
The smaller river (stream) is a tributary of the main river.
Tributaries
Streams are merely tributaries of rivers. A river is the wider channel into which smaller creeks, streams and rivers flow. (Streams do not flow out of rivers.) Streams carry water from higher sources, emptying into the river. As more streams empty into a river, it tends to become broader, simply because of the greater volume of water it is carrying.

A large stream of surface water is usually called a river. A river is freshwater and runs from high to low ground.
River
A river is formed when water draining from mountanous terrain or some other watershed flows into a valley via smaller streams. The streams join together and their combined volume of water forms a river with the force of the water cutting a channel as it flows downhill toward a lake, sea, or ocean.

If a rock falls into a stream or river, they can get transported (carried away). As they are moved by the water, the rock fragment knock against each other and wear away. This is called ABRASION. This bits of rock or sand in streams are called Sediment.
Majority of rivers and streams have fresh water flowing in them.
It is usually the other way round. Moving in the direction of water flow, streams merge together to form larger rivers, the streams are called the river's tributaries. The point of joining is called a "confluence".
Lakes, rivers, and streams are bodies of water.
