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

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. Rivers
