Near its end, the river slows down and deposits sediment. This can form a delta , a fan-shaped area of fertile land, before the water finally empties into a lake or the ocean. Why Rivers Matter Rivers

As the terrain flattens, the river gains more water from tributaries —smaller streams that join the main flow. Here, the river begins to meander , creating wide loops as it erodes its banks. Rivers are essential for both the natural world

Every river follows a predictable path driven by gravity, flowing from high elevation to low elevation through three distinct stages: Here, the river begins to meander , creating

Often starting as melting glaciers, springs, or rainwater in mountains, rivers in this stage are narrow and fast-moving, cutting steep V-shaped valleys through erosion.
