Which is the older the grand canyon or the rock layers now exposed on the canyon walls?

Are the rock formations in the grand canyon older at the top or bottom of the canyon?

The rock formations at the bottom are older.

Is the grand canyon older than the US?

Yes.

If in the Grand Canyon walls if a fossil imprint of a leaf is lower than a shell fossil does that mean that the leaf fossil is older than the shell fossil?

Not necessarily. The relative position of fossils in the rock layers can provide clues about their age, but it is not a definitive indicator. To determine the actual age of the fossils, scientists often use radiometric dating techniques and other methods to establish a more accurate timeline.

How would you know which rock layer in a canyon is the oldest?

The oldest rock layer in a canyon is typically the layer found at the bottom. This is because new layers of rock are deposited on top of older layers over time, resulting in a sequence with the oldest rocks located at the base of the canyon. Geologists use principles of stratigraphy, such as the Law of Superposition, to determine the relative ages of rock layers in a canyon.

What does the Grand Canyon look like?

What is unique about the geologic record at Grand Canyon is the variety of rocks present, the clarity with which they are exposed, and the complex geologic story they tell.Two separate geologic stories exist at Grand Canyon. The older story is the one revealed in the thick sequence of rocks exposed in the walls of the canyon. These rocks provide a remarkable record of the Paleozoic Era (550 - 250 million years ago). Scattered remnants of Precambrian rocks as old as 2,000 million years can also be found at the bottom of the canyon. The story these rocks tell is far older than the canyon itself. Mesozoic and Cenozoic rocks (250 million years old to the present) are largely missing at Grand Canyon. They have either been worn away or were never deposited.The second geologic story at Grand Canyon concerns the origin of the canyon itself: when and how did it come to be? On one level the answer is simple: Grand Canyon is an erosional feature that owes its existence to the Colorado River. Of equal importance are the forces of erosion that have shaped and continue to shape the canyon today. These include running water from rain, snowmelt, and tributary streams which enter the canyon throughout its length. The climate at Grand Canyon is classified as semi-arid. The South Rim receives 15 inches / 38 cm of precipitation each year. The bottom of the canyon receives 8 inches / 20 cm. The rain comes suddenly in violent storms, particularly in the late summer of each year. The power of erosion is therefore more evident here than in other places which receive more rain.Grand Canyon owes its distinctive shape to the different rock layers in the canyon walls. Each responds to erosion in a different way: some form slopes, some form cliffs, some erode more quickly than others. The vivid colors of many of these layers are due mainly to small amounts of various minerals. Most contain iron, which imparts subtle shades of red, yellow, and green to the canyon walls. Climate plays an important role in the appearance of the canyon. If there was a higher amount of precipitation at Grand Canyon, the plants and trees that grow here would be very different. The canyon walls might be covered with lush vegetation, rather than the cacti and shrubs growing there today.How old is the canyon itself? The early history and evolution of the Colorado River (of which Grand Canyon is only a part) is the most complex aspect of Grand Canyon geology. We know that the erosion which has shaped the canyon has occurred only in the past five to six million years. This is only yesterday, considering the age of the rocks through which the river has carved.Grand Canyon continues to grow and change. As long as rain and snow continue to fall in northern Arizona, the forces of erosion will continue to shape Grand Canyon.from:http://www.grand.canyon.national-park.com/geology.htmYou can find also amazing photos at the link below:

Does plate shifting cause previously unseen rock layers to be exposed?

Yes, plate shifting can cause previously hidden rock layers to be exposed through processes such as uplift, folding, faulting, or erosion. This can reveal older rock layers that were buried beneath the Earth's surface.

How old is the history of the Grand Canyon?

thats an enigma...since the deeper the river gouges into the terrain the older it becomes...in reality the younger its archeological findings will be in respect to the age of the Earth...! Humn!?!

How the law of superposition helps scientist determine relative age?

Younger layers are deposited on top of older layers, whether the layer is sedimentary or volcanic. Occasionally faults may result in overthrusts, where a series of older layers may be pushed over the top of younger layers. But this is rare. In general, the older layers will be the lower layers.

Which is older cactus hill or nottoway canyon?

Cactus hill

Are older fossils found in higher layers of earth or lower layers?

Why is the sedimentary rock layer at the bottom of a canyon older then a sedimentary rock layer at the top of a canyon?

As a rule, the oldest rocks of layered rock strata are always at the bottom, the youngest at the top. The rock at the bottom was the first to form. Layers of weathered and eroded particles (sediments) or igneous material in the form of lava, add additional weight over time, which causes the mass to sink and compress, forming new rock layers. When running water erodes a canyon, the geologic history of the land is revealed in the rock layers.

Would you expect to find fossils of an organism that lived relatively recently in old layers of rock or in younger layers?

Fossils of an organism that lived relatively recently would be expected to be found in younger layers of rock, as they would not have had sufficient time to become buried and fossilized in older layers. Fossils of older organisms tend to be found in deeper, older layers of rock.
