Grand Canyon Grand Canyon is an exceptionally dep, steep walled canyon in north western Artzona, United States Formed by the creding action of the Colorado River, the Grand Canyon is about 443 km (227 mi) long 8 to 29 km to 18 mil) wide, and more than 16 km (mil) deep The entire canyon is extremely beautiful. containing towering buttes mesas and valleys within main gonge A spectacular section of the canyon, together with plateau areas on either side, is preserved as the Grand Canyon national Park, which receives aboue 4 mullion visitors a year The Grand Canyon stretches 340 km (7 mil) across the state's Colorado Plateau and averages 16 km (10 mil) in width Beautiful mock formations of layered limestone, sandstone, shals and other rock rise from the canyon floor, which is more than 10 km (I mul deep This formation is known as "The Alligator". The Grand Canvon curs steeply through an arid plateau region that lies berween about 1525 and 2.745 m (5.000 and 9000 ft) above sea level . This region, although lacking year round streams in recent years, is sharply ended, showing such characteristic forms as buttes, it is interspersed with old lava tlows, bills composed of volcanie debris and intrusions of igneous rock. The plateau area has a general downward slope to the south west and in its upper reaches is sparsely covered with such evergreens as juniper and pinon Parts of the valley consist principally of such desert plants as agaves and Spanish bayonet. In general the entire canyon area has little soil . The climate of the plateau region above the canyon is severe, with extremes of hoth heat and cold The canyon floor also becomes extremely hot in summer, sometimes reaching 46 C(115*5), but seldom experiences frost in the summer. The Grand Canyon has been sculpted in general by the downward cutting of the Colorado River, which flows the canven's lowest portions Other factors have also played a part. The Kaibab Plateau, which forms the northern rim of the canyon, is abour 365 m (1.200 ft) higher than the Coconino Plateau, which forms the southern rim. Water from the northern side has flowed into the canvon, forming tributary vallevs while the streams of the southern plateau flow away in a southerly direction without carving valleys in the canvon walls The underlving rock beds also have a south western sant, with the result that groundwater from the north finds its way into the canvon, but water from the south does not in the entire canyon region, the rocks have been by jointing and faulting and fractures in the rocks resulting from these processes have contributed to the rapid erosion of the gorge. 1. what is the purpose of the text above? 2. where is the location of the grand Canyon? 3. mention types of stone risen from the canyon! 4. what temperature can be reached by the canyon's floor at summer? 5. what is the name of the plateau that from the northern rim of the canyon?mohon bantuannya ​
