What type of weathering is primarily responsible for the formation of this canyon? a. Frost wedging b. Chemical weathering c. Mechanical weathering from air d. Mechanical weathering from water We can measure the rate of erosion in this canyon at about 0.01 inches/year. Based on this rate, approximately when did the canyon start to erode? (Hint: Measure the difference in elevation from the bottom of the canyon at the latitude and longitude given above and the top, measured at the road of the edge of the canyon due south of the previous point. Then divide by the rate of the erosion. Make sure to use the correct units.)  a. 750,000 years b.

What type of weathering is primarily responsible for the formation of this canyon?

a. Frost wedging b. Chemical weathering
c. Mechanical weathering from air d. Mechanical weathering from water

We can measure the rate of erosion in this canyon at about 0.01 inches/year. Based on this rate, approximately when did the canyon start to erode? (Hint: Measure the difference in elevation from the bottom of the canyon at the latitude and longitude given above and the top, measured at the road of the edge of the canyon due south of the previous point. Then divide by the rate of the erosion. Make sure to use the correct units.) 

a. 750,000 years b. 1,200,000 years c. 2,700,000 years d. 3,500,000 years

Black Canyon of the Gunnison National Park is located in which of the following
physiographic provinces?

a. Blue Ridge b. Colorado Plateau c. Appalachian Plateau
d. Rocky Mountains e. Basin and Range f. Columbia Plateau

Black Canyon of the Gunnison National Park Black Canyon of the Gunnison National Park (Figure 14.12) is located in Western Col- orado and was established as a National Park in 1999. This park is often overshadowed by the Grand Canyon, but is striking in its own right. The Gunnison River has a high gradi- ent, which has produced an incredibly steep canyon. In fact, it is called Black Canyon not because of the color of the rocks, but because of the dark shadows produced by the steep walls of the canyon.
