Grand Canyon Case Study

Grand Canyon is located in north Arizona, the Grand Canyon is known throughout the world for its size and colorful landscape. It is said that Grand Canyon was formed over 17 million years ago and until recent year; it was only thought to be 4-6 million years old. Grand Canyon is over 270 miles long, up to 18 miles wide and 1 mile deep. After you have read how big Grand Canyon actually is, you may be wondering: How was it formed? And that is a very good question. The answer is quite difficult, but the thing that had the most impact on Grand Canyon is erosion. You may not know what erosion is so I will explain it in case you did not know.
Erosion is the process by which the surface of the Earth gets worn down. Erosion can be caused by natural elements such as wind and glacial ice. But the element that had the most impact to Grand Canyon is water. Then you may think: the Grand Canyon is basically located in the desert, so how can water have the most impact if Grand Canyon is located in the desert?
Because the soil in the Grand Canyon is scorched by the sun it becomes very hard and cannot absorb water when the rain comes. The plants that grow in the Grand Canyon have very shallow root systems so that they can absorb as much water as possible on those rare occasions when it does rain.
The skywalk is a horseshoe-shaped that is 4000 feet above the canyon floor in the Grand Canyon West area of the main canyon. This may be able to sound a little crazy but the skywalk could support the weight of more than 70 Boeing 747 passenger jets, according to engineers. At the skywalk you can witness the majestic view of the beautiful layers of rock Grand Canyon has. It is said that the top layer of rock is Kaibab Limestone and is around 240 million years old, and the bottom layers of rock is named Vishnu schist and it is about 1.7 billion years
