The exposed rock layers at the Grand Canyon are at least about two billion years old. A good 13,000 feet of sediment and lava were first deposited in coastal and shallow marine environments, e.g. NOT inside the Grand Canyon. Earth's folding (which caused the mountains) brought sediment from the Pacific side. Streams and rivers brought sediments from the Appalachian Mountains in the east, which were folded from both the Pangaea-times sea located in the middle of the country and the Pacific Ocean.
What else can I help you with?
What exposed all the rock layers in The Grand Canyon?
Erosion, caused by wind and water.
How much geologic time do layers of rock exposed at the Grand Canyon represent?
The age of the rock layers exposed in the Grand Canyon range from 240 million years to 1,800 million years in age. The surface feature known as the Grand Canyon is thought to be less than 17 million years old.
Which is the older the grand canyon or the rock layers now exposed on the canyon walls?
The rock layers exposed on the walls of the Grand Canyon are significantly older than the canyon itself. The rock formations, such as the Vishnu Schist, date back about 1.7 billion years, while the Grand Canyon was primarily formed over the past 5 to 6 million years through erosion by the Colorado River. Thus, the canyon is much younger than the ancient rocks it reveals.

What kind of rock is Grand Canyon made out of?
Rocks exposed in the Grand Canyon include limestones, cherts, shales, schists, sandstones, and granites.
Is there limestone in the Grand Canyon?
Yes, there is limestone in the Grand Canyon. It is primarily found in the form of the Redwall Limestone layer, which is one of the prominent rock layers in the canyon.
Why is the Grand Canyon important in the past?
it's layers of rock tell us about the past
What type of rock form layers that can be seen in heavily weathered regions such as the grand canyon?
Sedimentary
Was the Grand Canyon once an ocean?
No, the Grand Canyon was not once an ocean. It was formed by the Colorado River cutting through layers of rock over millions of years.
In the Grand Canyons the oldest fossils are found where?
The oldest fossils in the Grand Canyon are found in the layers of sedimentary rock near the bottom of the canyon, dating back around 1.2 billion years ago. These fossils provide insights into early life forms and the geological history of the region.
