Two characteristics of the Grand Canyon of Colorado
Answers
Answer:
The Grand Canyon is indeed a very big hole in the ground. It is 277 miles (446 km) long, up to 18 miles (29 km) wide and more than a mile (6,000 feet / 1,800 meters) deep. It is the result of constant erosion by the Colorado River over millions of years.
Grand Canyon is noted for its fantastic shapes and coloration.
1) It is considered one of the finest examples of arid-land erosion in the world. Incised by the Colorado River, the canyon is immense, averaging 4,000 feet deep for its entire 277 miles. It is 6,000 feet deep at its deepest point and 18 miles at its widest.
2) In its general color, the Grand Canyon is red, but each stratum or group of strata has a distinctive hue—buff and gray, delicate green and pink, or, in its depths, brown, slate-gray, and violet.
