What has the most impact on the rock layers of the Grand Canyon?
The Colorado River has carved the Grand Canyon into four plateaus of the Colorado Plateau Province. The Province is a large area in the Southwest characterized by nearly-horizontal sedimentary rocks lifted 5,000 to 13,000 feet above sea level.
Why are the rock layers in the Grand Canyon different but yet most of them are a red color?
Grand Canyon owes its distinctive shape to the different rock layers in the canyon walls. Each responds to erosion in a different way: some form slopes, some form cliffs, some erode more quickly than others. Most contain iron, which imparts subtle shades of red, yellow, and green to the canyon walls.
Why is the inner gorge of the Grand Canyon so steep?
The extremely hard metamorphic rocks at the bottom of the canyon produce the steep-walled and narrow Inner Gorge, as these rocks are more resistant to erosion than the softer sedimentary rocks above. As a result of these dams, the dynamics of the Colorado River through Grand Canyon changed dramatically.
