the second anserer is correct but I gave you in more detail incase you want to learn more.
great gorge of the Colorado River, one of the natural wonders of the world; c.1 mi (1.6 km) deep, from 4 to 18 mi (6.4—29 km) wide, and 217 mi (349 km) long, NW Ariz. The canyon shows in its rocks the repeated geological sequence of uplift, erosion (due to the river's constant wearing force), submergence, and deposition of materials. The multicolored rocks, the steep and embayed rims, and the isolated towers, mesas, "temples," and other eroded rock forms catch the contrast of sun and shadow and glow with changing hues of great beauty. Plant life on the canyon walls varies from subtropical at the base to subarctic near the rims. Hundreds of ancient pueblos dot the lower canyon walls and the rim, and the Havasupai people still occupy a part of the canyon. The first European to see the canyon was the Spanish explorer García López de Cárdenas in 1540. In 1869 the U.S. explorer John Wesley Powell became the first person to lead a party through the canyon bottom in a boat.
The Grand Canyon was set aside by the U.S. government in 1908 as a national monument. In 1919 an expanded area was designated Grand Canyon National Park (1,217,403 acres/492,876 hectares). The park was enlarged in 1975 to include other areas, such as Marble Canyon and parts of Glen Canyon and Lake Mead. Along the forested northern rim and the more accessible southern rim are numerous lookouts, and trails wind to the canyon floor. Raft and boat excursions along the canyon's river bottom are popular. In 2000 the lands north of the western portion of the canyon, an area almost the size of the park, were designated Grand Canyon—Parashant National Monument (1,014,000 acres/410,670 hectares

The Grand Canyon is a colorful, steep-sided gorge, carved by the Colorado River, in northern Arizona. The canyon is one of the seven natural wonders of the world and is largely contained in the Grand Canyon National Park — one of the first national parks in the United States. President Theodore Roosevelt was a major proponent of the Grand Canyon area, visiting on numerous occasions to hunt mountain lions and enjoy the breathtaking scenery

No, the Grand Canyon is a major river (the Colorado River) flowing through a major mountain (the Kaibab Plateau), and in the process creating a major canyon (the Grand Canyon).

No. The grand canyon is like a very large crack in the earth.

It is a river canyon. The Colorado river has over millions of years eroded away the dirt and rock of the region.
