What contributed to the formation of the Grand Canyon?
Scientists know that the Colorado River carved Grand Canyon. The age of the river falls between the rocks determined to be older than the river and those determined to be younger. Through this method, scientists have estimated an age for the river, and thus the canyon through which it flows, of 5-6 million years.
What processes work together to form a canyon?
Most canyons were formed by a process of long-time erosion from a plateau or table-land level. The wind and water from the river combine to erode and cut away less resistant materials such as shales. The freezing and expansion of water also serve to help form canyons.
What process do scientists believe caused the Grand Canyon to form?
