if the Grand Canyon was created by water erosion from the Colorado river, then how come there isn’t grand Grand Canyons around all or most major rivers?
In: Earth Science
The river is not the important thing that created the Grand Canyon, it is the type of bedrock. It is rock that is easily eroded by water but still strong enough that it does not collapse and the eroded sediments does not settle in slow moving parts of the river. This have allowed the river to flow through the same path for millions of years and carve out the canyon to its current depth. If you look at other great rivers they usually go through softer soil which means the river banks collapses and the sediments settle so the rivers move all the time eroding the entire area evenly. The Grand Canyon is not the only such geological feature in the world.
