Q:

Why are rivers important?

A:

Quick Answer

Rivers are important because they transport water, provide habitat, support economic activities and enable transportation. Rivers provide life-sustaining supplies of water and important nutrients for living organisms around the world, including humans, plants and fish. Large rivers provide power for hydroelectricity and facilitate the movement of people and goods within nations and across borders.

Full Answer

Regardless of location, rivers transport water and nutrients to areas across the earth. They essentially form the basic building blocks of the water cycle by serving as drainage channels for surface water. Rivers also play helping roles in alleviating conditions such as flash floods by absorbing excess water, and they change shape to accommodate changing geographical features of surrounding lands.

Rivers and streams also provide habitat to many organisms, ranging from small, unicellular creatures to insects, vegetation, fish and mammals. Rivers and streams are often breeding grounds for rare and exotic species of plants and trees and serve as home to ducks, beavers, otters and other creatures that build shelters along their shorelines. Rivers also support economic activities: they supply irrigation to enable small- and large-scale farming operations to take place and may generate enough power to create electricity. Rivers also serve as key transportation routes by enabling exploration, recreational activities and commercial ships.

  • Q:

    Where do rivers come from?

    A:

    Rivers are freshwater bodies that primarily form due to surface precipitation runoff. When rain falls or snow melts, the water either infiltrates into the ground or collects into small puddles that grow in size and become rivers. Due to the action of gravity, these bodies of water naturally flow downstream through various channels before they eventually empty into the sea.

  • Q:

    How do rivers form?

    A:

    Rivers form when flowing water from precipitation or springs flows over land and accumulates in existing low points in the topography, eroding it and forming a riverbed. Rivers are channels for moving water, which always seeks to flow downhill, and indeed, many rivers start from small channels in mountains. As it erodes the landscape, different aspects of the interaction between flowing water and the ground cause winding and branching.
