How long did it take for the grand canyoon to form?

Answer 1

The Grand Canyon formed over millions of years, primarily through the erosive processes of the Colorado River, which began carving the canyon around 5 to 6 million years ago. However, the geological history of the area goes back much further, with rock layers dating back nearly 2 billion years. The combination of river erosion, geological uplift, and climatic changes contributed to its current shape and depth. Thus, while the river's erosion is a more recent process, the canyon's formation is a result of a much longer geological timeline.
