How can a river change the landscape?
|
|
Rivers begin with water flowing downhill. Young mountain streams often originate in glaciers. The swiftly flowing water can carve away rock and produce deep V-shaped valleys. As it reaches the hills, it moves more slowly, producing broad valleys. When the river reaches flat plains, it may meander in wide curves. If a curve becomes cut off, it forms a lake. As a river reaches the sea, it deposits stones and sand to form a delta of low land along the coast.
