Streams are important for several reasons: Streams carry most of the water that goes from the land to the sea, and thus are an important part of the water cycle. Streams carry billions of tons of sediment to lower elevations, and thus are one of the main transporting mediums in the production of sedimentary rocks. Streams carry dissolved ions, the products of chemical weathering, into the oceans and thus make the sea salty. Streams are a major part of the erosional process, working in conjunction with weathering and mass wasting. Much of the surface landscape is controlled by stream erosion, evident to anyone looking out of an airplane window. Streams are a major source of water and transportation for the world
Summary Streams carry water and sediment downslope Streams are important since they erode and deposit materials shaping the earth’s surface and they are a source of water and transportation to humans Streams are part of the hydrologic cycle In general streams have a geometry based on the rock types they flow through and the amount of water they discharge Streams also flood, producing hazards and human activities and land uses should take into account hazards associated with flooding
