These Rivers and streams erode the land as they move from higher elevations to the sea. Rivers and streams have many of the same economic, recreational, and environmental values and uses as lakes. Drying and flooding largely drive the temporal variability in IRES physicochemistry. Everyone wants lakes, rivers and streams that are safe to swim in, gather food from, and that support healthy ecosystems. In particular, low flows are more frequent, are of shorter duration, and vary less from one year to the next than they Students determine the main idea of “Rivers and Streams,” annotate their text, and answer questions using specific details from the text.
