How did the Grand Canyon rock form?

Answer 1

It seems that the Grand Canyon was formed by two major geologic events occurring over the same very long period of time. Recent evidence indicates that the two billion years of the Earth's history that is now exposed began to be exposed some 17 million years ago as the Colorado River and it's tributaries flowed over the Colorado Plateau while it was itself being uplifted. As the land rose, the Colorado River - and it's tributaries - cut through to form the canyon as we know it today.

Answer 2

Every rock strata above the basement granite and schist at the bottom is sedimentary, either deposited on an ancient shoreline, ocean floor, or swamplike area over hundred of millions of years. The rock strata have become exposed through the cutting action of the Colorado River over the past 13 million years, according to the most recent scientific information available.

Answer 3

The Grand Canyon rock was formed by the deposition of layers of sediment over millions of years. The Colorado River then carved through these layers, revealing the different types of rocks and creating the canyon we see today.

Answer 4

The colorado river rushed through it
