What is the name of the geologic process that formed the grand canyon?

The Grand Canyon was primarily formed by a geologic process known as erosion, primarily through the action of the Colorado River over millions of years. This process involved the river cutting through layers of rock, exposing various geological formations. Additionally, factors such as weathering, tectonic activity, and the uplift of the Colorado Plateau contributed to the canyon's development. The result is a stunning landscape showcasing Earth's geological history.
