How Did The Grand Canyon Form?

The Grand Canyon, located on the Colorado Plateau, is a vast geological formation shaped by tectonic activity, erosion, and the Colorado River over millions of years. Initially formed by the collision of the Pacific and North American plates, mountain ranges were created and later eroded by glaciers and rainfall, forming a plateau. The Colorado River, originating in the Rocky Mountains, carved through this plateau over 50 million years, aided by flash floods and ice, to form the Grand Canyon. This process resulted in a canyon 29 kilometers wide and 446 kilometers long, showcasing rocks over 2 billion years old.
