The Grand Canyon(科罗拉多大峡谷) is a large river canyon in Arizona. It is over 220 miles long and over a mile deep in some places. Its widest point is 18 miles wide. The canyon is considered one of the Seven Natural Wonders of the World.
Over millions of years, The Colorado River wore away rocks as it passed through the area. Slowly, the river made the path deeper and deeper. Now, the canyon is surrounded by steep walls on either side, while the river continues to flow at the bottom of the canyon.
Besides its large size, The Grand Canyon is also known for its magnificent colors. The Canyon is made of layers of rock(岩层), and each layer of rock has a different depth and color. Geologists have identified almost different layers of rock exposed by the river’s erosion.
The climate is canyon area is primarily desert, with both high and low temperatures. The upper rims of the canyon often receive snowfall. The air quality is usually very high, although dust storms and smoke from fires can change the air.
The Grand Canyon is home to a variety of plants and animals. Plants range from various species of cactus to pine forests. Many types of animals live in the area, including the bald eagle, bobcats, bats and gila monsters. Six different kinds of rattlesnakes have been found in the area.
