The Earth’s greatest gorge” the Grand Canyon is located in northwestern Arizona. Its vastness is 217 mile long, and its widest it spans over 17 miles across. It is not surprising that it has been designated one of the Seven Wonders of the World.
The walls of the canyon are made of limestone, sandstone, lava and other rocks. As the day passes the rocks reflect different colors. Many tourists come to the canyon just to watch the rocks change color.
Cottonwood and willow trees grow at the bottom of the canyon. Many varieties of cactus grow here as well. The canyon is also home to many animals, such as bobcats, coyotes, kangaroo rats and deer.
Today about 4 million visitors come to the Grand Canyon each year. Seeing the Grand Canyon is always a breathtaking and unforgettable experience.
Tornadoes A tornado is a very powerful column of winds which spirals around a center of low atmospheric pressure. It is one of the most destructive storms on earth. A tornado is also called a waterspout.
A tornado is a long cloud which comes down from the sky. It is shaped like a funnel and consists of wind which whirls around and around extremely fast. In fact, the wind can reach a speed of more than 900 km per hour.
Most tornadoes from a long a front(boundary) between cool, dry air and warm, humid air. Weather scientists are unable to know exactly when tornados will occur. Fortunately, the tornado is not usually very big and it does not last long.

The Grand Canyon is a canyon divided by the Colorado River flowing at its bottom and its walls are decorated by different color layers of rock. It is due to this rock deposition and layering that the canyon has become a spot for geologist to study and of great tourism. As you can see in the image below, the canyon has eighteen (18) different rocks layers and three (3) sets of rocks. At the very bottom it’s the Vishnu basement rocks that date back to approximately 1,200 million years in age, which denotes the earliest rock sediment for the canyon in that area. At the very top is the Kailab limestone dating 270 million years ago. This limestone was actually formed under the ocean as geologists have discovered. But due to tectonic plate action, the plateau was uplifted and the canyon gradually changed over the years. Today the kailab limestone rises up to 9,000 feet in height.…

According to Sid Perkins, an earth science writer, the canyons deepest parts are 1.7 billion years old and the Canyon its self only40 million years old. The canyon shows off many layers of limestone that each have a unique story, “Thick bands of limestone speak of lengthy eras spent beneath broad, shallow seas or still, clear lakes. Beds of lava and ash recount episodes of widespread volcanic activity.Other layers of rock show that this grand swath of real estate has also been home to coastal mudflats and windblown sands (Perkins, “Making”)”. These layers can be measured and told apart by mammillaris, which are lumps of carbonate minerals. These lumps mark the level of the local water table (Perkins, “Parts”). Another piece of data that may help us determine when the canyon began to form is locked in a layer of limestone filled with algae and sediments that thrive in only fresh water lakes. This ‘Muddy Creek Formation’ has been aged with radioactive dating, which puts it between 6 and 11 million years old. This theory that the river could not have been carving the canyon while a lake was present was presented by Richard Young a geologist at the State University of New York (Perkins,…
