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.

Is the lowest point of the Grand Canyon below sea level?
At it's deepest, the lowest area of the Grand Canyon is over 6,000ft below the canyon rim.
Which river forned the Grand Canyon?
One of the common theory's is that the Colorado River carved the Grand Canyon, yet this is not a fact. There are other theory's how the Grand Canyon was formed. One Theory suggests that there was three great lakes in Arizona, Utah, New Mexico and partly in Colorado. The Kiabab Uplift created a natural dam. The Kiabab Uplift eventually breached and formed the Grand Canyon in a matter of a short time.
Both theory's have holes in them.
River flows through the grand canyon?
"it is called lempive" (by ID1255502964) ACTUALLY, it's called the Colorado River.
What time does the Grand Canyon open?
After having having visited this place six times, I recommend two days an optimal for the non-backpacker. One day to visit sights on the South Rim, and one day to walk down a trail (South Kaibab or Bright Angel) until fatigue STARTS, then returning back. The latter gives a much better experience on the actual size of The Canyon.
If willing and prepared to do desert canyon hiking, one can do weeks of back-packing in this place.
What elevation is the river at nankoweap canyon?
the actual answer is 2,800 feet. It was on my paper. Your Welcome! :)
How many people visit the grand canyon in the summer?
10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,001
Is Grand Canyon a common noun?
No, Grand Canyon is a proper noun; it is the name of a specific place, names are always proper nouns. A proper noun is always capitalized.

What is the geomorphology of the Grand Canyon?
The Grand Canyon is a canyon, as the name implies.
Also,
On the B.O. Scale for geographical features, the Grand Canyon rates as a "HH". The scale is as follows:
HL Humongous Lump
LL Large Lump
SL Small Lump
P Pancake
SH Small Hole
LH Large Hole
HH Humongous Hole
The formation of the Grand Canyon was accomplished by the constant erosion of the rock by the Colorado River over some 17 million years. Over time the river was able to carve a very deep channel into the Colorado Plateau. Links are provided to specifics regarding the geology of the Grand Canyon.
What languages are spoken in the region near the Grand Canyon?
The Havasupai people are the only permanent inhabitants of the Grand Canyon, and they speak Havasupai–Hualapai language, as well as English.
Can you fly to the Grand Canyon?
The nearest cities to the Grand Canyon South Rim are Tusayan, Williams and Flagstaff. The nearest cities to the Grand Canyon North Rim are Page, Arizona and Kanab, Utah.
It looks like Flagstaff would be the best airport to try.
How many miles from the Grand Canyon to 4 Corners?
It's about 250 highway miles from the 4-Corners to the main settlement of the Grand Canyon (the area with all the hotels and development on the South Rim). The Grand Canyon itself is over 100 miles long, though, so parts of it are closer and parts are farther. The North Rim would be a much longer drive, for instance.
What is the chemical weathering of the Grand Canyon?
The Grand Canyon is primarily an example of river erosion - the Colorado River runs through the bottom of the canyon and carved the whole canyon over thousands of years. However, the exposed rock has also been weathered by wind and rain for thousands of years.
Is part of the grand canyon in Las Vegas?
No, part of the Grand Canyon is not in Las Vegas. The Grand Canyon is located in northern Arizona, approximately 250 miles from Las Vegas. While Las Vegas is a popular starting point for tours to the Grand Canyon, the canyon itself lies entirely within Arizona.
Should you go to the North rim of the Grand Canyon or the south rim?
The answer depends on what you mean by "better."
The North Rim is higher, cooler, more isolated, more arboreal, and has far fewer visitors. It also has fewer tourist facilities, which is a plus or a minus depending on how you view their presence.
Which rim has better views is subjective, but most people think the most iconic viewpoints are on the South Rim.
What was the Grand Canyon like 100 years ago?
There would be very little noticeable difference to the human eye.
What are some nonliving things in the Grand canyon?
Yes
HAVASUPAI
The "People of the Blue-Green Waters" live in Havasu Canyon in the middle of Grand Canyon. They continue to farm as they have for centuries, but also work in the cattle, forestry and tourist industries. They are well-known for their basketry and beadwork, the waterfalls on their reservation. Supai is accessible on foot, on horseback, or via helicopter.
HOPI
The Hopi are peaceful farmers directly descended from the ancestral Puebloans (Anasazi). Their lifestyle on the mesas is typical of Pueblos. Considered the most adept dryland-farmers in the world, they grow corn in mostly non-irrigated plots (depending on the summer rains) at the base of the mesas. The small Hopi Reservation is concentrated in Pueblos on three mesas in northeastern Arizona and is completely surrounded by the Navajo Reservation.
Old Oraibi has been occupied since A.D. 1150, making it one of America's oldest continuously inhabited villages. The Hopi are renowned for their silverwork, elaborately designed pottery and kachinas, which are wooden ceremonial spirit dolls.
HUALAPAI
The Hualapai live just south of the western portion of the national park. Farming, cattle-raising, forestry and tourism are their primary occupations. Their celebrated basketry has evolved from their hunter-gatherer tradition. They are also known for their exquisite dolls.
KAIBAB-PAIUTE
The Kaibab-Paiutes live north of Grand Canyon on the Arizona Strip. Their reservation lies adjacent to Pipe Spring National Monument, a historic western ranching operation built up around an 1870 fortified dwelling. The hunter-gatherer origins of the Paiutes are most evident in their prized "wedding baskets" and other basketry.
NAVAJO
Some Navajo continue to live in traditional six- or eight-sided houses, known as hogans, and raise sheep, goats and corn. The 16-million-acre Navajo Reservation, located near the East Entrance of the park, is the largest of any southwestern tribe. Some of the numerous scenic and historic attractions are Monument Valley, Canyon de Chelly, Little Colorado River Gorge, Rainbow Bridge in Glen Canyon, dinosaur tracks near Moenave, Grand Falls and Window Rock (Navajo Tribal Headquarters). The Navajo are famous for their finely woven rugs, silver and turquoise jewelry, and sand paintings.
How long does it take to fall down the Grand Canyon?
133 meters = 0.5(9.8)time^2. Time in seconds = approx. 5.21 seconds, assuming that wind resistance is not an enormous issue.
What two lakes are at the ends of the Grand Canyon?
Lake Mead is the largest, followed by Lake Powell.
