What is a Canyon Landform?


The striking features of a canyon are very steep cliffs with deep valleys running through them. They are formed where rocks are stratified horizontally and are associated with rocks that do not have uniform resistance to erosion.

Canyon landform for children
The valley may or may not have water in them. Canyon can be seen both on land (usually called River Canyons) and on the ocean floors (also called submarine canyons). Canyons are also known as gorges, or mountain canyons
.
Canyon formation by erosion River canyons form when the pressure of a river cuts a deep and narrow channel through its bed. Rivers usually flow from high elevation to low elevation. Thus, the erosive power of a river is more as it runs downhill. With time, it will erode its bed until it is at the same elevation of the bigger water body into which it drains

A few of the world's spectacular canyons include
1. Colca Canyon, Peru is 13,650ft deep and 45 miles long

2. Grand Canyon, Arizona USA, is about 5,249ft deep and about 277miles long
3. Fish river Canyon, Namibia, is about 1800ft deep and 100miles long
