The Parts of a River are above! Rivers are habitat for different animals and plants.
Rivers help the growth of civilization. Rivers were used for drinking water and to bath or shower with. Some civilizations had there own sewage systems which dumped human waste into the rivers. The rivers then carried it away from the city. Some rivers come long distances and bring with them Clay, Silt and Sand. These help produce fertile soil which is used for the civilizations agriculture so that the civilization can grow food to feed itself and to trade to other civilizations.
Some rivers which do this are the Indus river and the Nile river.
