How does a river valley change with time?

In this condition, more energy is expended laterally than vertically, and a river progressively broadens its valley floor. As a result, most river valleys change over time from narrow forms to broader ones, the shape at any time being dependent on baselevel, rock type, and rock structures.

Often, waterfalls form as streams flow from soft rock to hard rock. This happens both laterally (as a stream flows across the earth) and vertically (as the stream drops in a waterfall). In both cases, the soft rock erodes, leaving a hard ledge over which the stream falls.

Why do rivers create V shaped valleys?

V-shaped valleys. Rivers begin high up in the mountains so they flow quickly downhill eroding the landscape vertically. The river cuts a deep notch down into the landscape using hydraulic action, when the sheer force of the water gets into small cracks and breaks down the sides of the river valley.

A river usually ends by flowing into an ocean, a lake or a bigger river. The place where the river flows out into a bigger body of water is called the 'mouth' of the river.
