State of being young; process of growing into a young person

1. The act of restoring to a more youthful condition.
2. The phenomenon of vitality and freshness being restored; SYN. greening.
In earth science, the renewal of a river's powers of downward erosion. It may be caused by a fall in sea level or a rise in land level, or by the increase in water flow that results when one river captures another (river capture).
Several river features are formed by rejuvenation. For example, as a river cuts down into its channel it will leave its old floodplain perched up on the valley side to form a river terrace. Meanders (bends in the river) become deeper and their sides more steep, forming incised meanders, and waterfalls and rapids become more common. + prikaži više
