Question

While visiting the Grand Canyon, you observe the exposed layers of rock on the valley. What natural process most likely caused the valley to form? Deposition Chemical weathering Oxidation Erosion

This would be either chemical weathering or erosion.

See, the rock was broken down and cracked by any sort of weathering or erosion. It could've been caused by either one of those, honestly.

Have a great day :)
