Much of Grand Canyon’s width has been gained through the erosive action of water flowing down into the Colorado River via tributaries In a few million years, Grand Canyon also may be a bit deeper, though the canyon isn’t getting deeper nearly as fast as it is getting wider
How did the Colorado River create the Grand Canyon?
The Canyon itself was carved by the Colorado River and the wind that caused the surface of the sedimentary rocks to become exposed and erode over time The erosion of the Grand Canyon by winds, rains and the amazing strength of the Colorado River created the marvelous views and exposed magnificent caves
Was the Grand Canyon once underwater?

Why is the Grand Canyon far wider than the river itself?
The strongest explanation holds that the major factor in the widening of the canyon has been activity from tributary drainage systems — the side streams, rivulets, and gullies outside the main river channel The greatest erosive force in these tributaries is the fast-moving landslide called a debris flow
How exactly was the Grand Canyon formed?
The Grand Canyon is a large, deep river valley in Northwestern Arizona The main cause of the erosion that formed the Grand Canyon was water; most scientists agree that it formed when the Colorado River started carving through layers of volcanic rock and sediment between five million and six million years ago

Was the Grand Canyon formed by deposition?
This incredible formation was carved over millions of years by the Colorado River The canyon itself has formed much more recently than the deposition of rock layers, only about five million years ago (as opposed to the rocks, the youngest of which are a little less than 300 million years old)
Does anyone live in the Grand Canyon?

Was Arizona once an ocean?

Is the Grand Canyon still forming?
