Why is the Grand Canyon important in the past?
it's layers of rock tell us about the past
How did david copperfield float over the grand canyon?
Only he knows and he won' t tell.
What can you tell me about the Grand Canyon Skywalk?
The Grand Canyon Skywalk is a transparent, horse shoe shaped bride that is located in Arizona. It is a popular tourist attraction that was opened on March, 28th 2007. The bridge closest major city is Kingman.
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:
How can you tell the earth has different layers using seismic data?
the earth is in solid and liquid form thus penetration is different tha:t account for the different earth layers.
What do scientist think will happen to the Grand Canyon in the future?
it is going to be a quite big place to stay
How can a film badge tell which type of radiation is being absorbed?
Different layers of materials have different absorbances for radiation.
What does the evidence found in places such as the Grand Canyon tell about Creation?
The fossils, geologic layers, and patterns of erosion found in the Grand Canyon indicate that a massive flood created the geological structure, not the billions of years claimed for uniformitarianism, with erosions and layering the strata. The theory of uniformitarianism is constantly being challenged and now being questioned, even by evolutionary scientists, because of the evidence being discovered today. The discovery also of such things as Saturn's rings evidencing a relatively young planet, makes the Biblical account of Creation much more viable in the scientific community, eliminating the possibility of billions of years for evolution's underlying uniformity theory.
Why is the Skywalk a somewhat controversial fixture of the Grand Canyon?
i dont know but if some1 finds out plz tell me in the comments sry im not helping at all but i rly need to know =P
What can you tell from undisturbed rock layers?
You can tell the age of the layers. The bottom layer is the oldest and the top is the youngest. When the layers are disturbed they tend to get bent and messed up and you cannot tell the age
How the layers of Earth formed the layers of Earth?
dust and ice and other partcials
What can layers of Arctic Ice tell us about atmospheric changes?
The different layers of ice can tell us a lot of things. They can tell us how much snow accumulated in a particular season, similar to looking at tree rings. They also contain atmospheric gases trapped in the ice. This gives an indication of the composition of the atmosphere at the time, since the ice can be dated.
