Explanation:
1. As the river erodes downwards the sides of the valley are exposed to freeze-thaw weathering which loosens the rocks (some of which will fall into the river) and steepens the valley sides. ... The rocks which have fallen into the river assist the process of corrasion and this leads to further erosion.
2.A gorge has rocky, steep walls caused by natural factors like erosion. A canyon is a narrow deep valley formed by water erosion or tectonic activity.
3.To gorge is defined as to consume or take too much of something, especially food. An example of gorge is when you eat an entire pie and cake all by yourself. The definition of a gorge is the narrow valley in between steep hills or cliffs. An example of a gorge is the Niagara Gorge.
4.Plunge pools are formed by the natural force of falling water, such as at a waterfall or cascade; they also result from man-made structures such as some spillway designs.[3] Plunge pools are often very deep, generally related to the height of fall, the volume of water, the resistance of the rock below the pool and other factors.
5. An oxbow lake forms when a river creates a meander, due to the river's eroding bank. After a long period of time, the meander becomes very curved, and eventually the neck of the meander becomes narrower and the river cuts through the neck, cutting off the meander and forming an oxbow
