What caused the shape of the Grand Cayon?

Answer 1

The Grand Canyon was formed when excessive and massive overflow of water washed off soft and loosen sandstone and dirt leaving hard ground intacted. As water continue down stream, soft sandstone and dirt get washed off and this created deeper channel as water decreases. At the same time water waves created and separated strata layers by bouncing and washing off loosen dirt between layers, making horizontal lines all the way from the top to the bottom. These horizontal lines prove that water did flood the area creating a massive canyon. A small river would not be able to create a several miles wide canyon. The fact that the top and bottom strata layers look identical in age suggests that the canyon may have been created at the same or not too distant set of times.
