Answer Details
The features commonly associated with river rejuvenation include knick points, which are abrupt changes in the river's gradient caused by uplift or other tectonic activity. Knick points create waterfalls or rapids in the river and are a visible sign of the river's rejuvenation process. As the river adjusts to the new gradient, it erodes the bedrock and creates other features such as paired terraces and entrenched meanders. Paired terraces are two parallel flat surfaces on either side of the river, formed by the river's lateral migration over time. Entrenched meanders are tight bends in the river that have been cut deeply into the surrounding rock or sediment, resulting in steep cliffs and narrow canyons. These features are all part of the river's rejuvenation process, as the river responds to changes in its environment and adjusts its course and behavior accordingly.
