Rivers, especially in their youthful stage, possess high erosive power due to steep gradients and fast-flowing water.
This erosive energy is primarily directed downwards, leading to the deepening of the river channel.
Gorges, also known as canyons, are deep, narrow valleys with very steep sides.
They are typically formed in the upper courses of rivers, where the river flows through hard, resistant rocks.
The process of formation involves vertical erosion (downcutting) by the river, driven by gravity and the river's momentum.
