Question: Name the underlying rock structure in which the grand canyon developed?

The Grand Canyon, a marvel of geology, developed on the Colorado Plateau Province, a region characterized by nearly-horizontal sedimentary rocks that have been lifted thousands of feet above sea level. These rock layers, which provide a comprehensive record of Earth's geological history, were carved by the Colorado River into the canyon's iconic steep walls and intricate formations. The oldest rocks at the canyon's base are Vishnu schist, which, along with other metamorphic rocks, were formed over 1.75 billion years ago. These ancient rocks were later intruded by igneous formations, creating a complex geological mosaic that is exposed in the canyon's deeper sections.
