Why is the Grand Canyon so deep?
The Grand Canyon is indeed a very big hole in the ground. It is 277 miles (446 km) long, up to 18 miles (29 km) wide and more than a mile (6,000 feet / 1,800 meters) deep. It is the result of constant erosion by the Colorado River over millions of years.
How can we tell how old rocks are?
To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events.
What are the rocks in the Grand Canyon?
The three main types of sedimentary rocks at Grand Canyon are sandstone, shale (or mudstone), and limestone. Metamorphic rocks are rocks that have been changed under great heat and pressure. The original rock can be sedimentary, igneous, or even metamorphic.

How long did the Grand Canyon take to form?
It has long been believed that the Colorado River began carving the Grand Canyon about 6 million years ago, but a 2012 study contained a real shocker, suggesting that the process may have begun as far back as 70 million years.
What are the rock layers?
In geology and related fields, a stratum (plural: strata) is a layer of sedimentary rock or soil, or igneous rock that was formed at the Earth’s surface, with internally consistent characteristics that distinguish it from other layers.

Remember, the oldest rocks in Grand Canyon are 1.8 billion years old. The canyon is much younger than the rocks through which it winds. Even the youngest rock layer, the Kaibab Formation, is 270 million years old, many years older than the canyon itself. Geologists call the process of canyon formation downcutting.
