Interesting fact: Canyons are deep gorges carved by rivers over millions of years, with the Grand Canyon being one of the most famous.
The answer: The weight of a canyon varies widely, but the Grand Canyon's rock mass is estimated to weigh around 1.5 quadrillion metric tons (about 1.65 quadrillion US tons).
A canyon is a deep valley with steep sides, often formed by river erosion. To estimate a canyon's weight, geologists calculate the volume of rock that forms its walls and floor, then multiply by the average density of the rock type, typically around 2.7 grams per cubic centimeter for granite and sedimentary rocks. The Grand Canyon, for example, stretches over 446 kilometers and reaches depths of over 1,800 meters, containing an immense volume of rock.
