The Life of a River
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Nearly all rivers have an upper, middle, and lower course (stages in the life of a river). The upper course is the beginning of a river – when it flows quickly with a lot of energy. The middle course is when the river gets wide and slows down. Rivers often meander (following a winding path) along their middle course. When a river reaches the end of its journey, it is at the lower course – an old river. At the mouth, there is often a river delta (a large silty area where the river splits into many different slow moving channels with muddy banks).
