Types of Canyons
Canyons of the World
Canyons are formed by erosion caused by rivers. Slowly, while eroding the river picks up light sediments and carries them downstream. Over a long period of time more materials are carried away ,aking the river deeper as well as wider. This process can tale a million, or even a billion years.
Canyons vary from how they look, their size, and what surrounds them. Canyons can be made up of different things. Many types of rock, and stone make up a canyon. Canyons can vary from range as well. A canyon can be very little or very big! Mostly all of the canyons in the world have stepped walls.

These make them different from the rest because they are formed a different way so they will look different. These canyons don't go very high.
Canyons of the oceans. They are cut into the ocean floor by currents. They are different from the others because of the way they are formed as well as the way they look. Submarine canyons are mostly blue in colour where as to the other canyons are brown, green, gray and colours like that.
These canyons are created by flash floods. They are not very wide but very deep. Powerful and fast moving flash floods. They are different because of the canyons depth. These canyons can be very deep!
