Thunderstorm over Conquistador Aisle in the Grand Canyon, Arizona. What kinds of structural features are most obvious in the rock? Which class of rocks is most clearly exposed? Has bedrock been removed from this landscape? How do you know? Why is it likely that both internal and external processes helped shape the Grand Canyon?

Conquistador Aisle in grand canyon is a structure made by the sedimentary rocks in the state of arizona.

Explanation:

The grand canyon is a steep-sided canyon and is made by the colorado river and is 227 miles long. Occurred due to the layers of rocks in the colorado plateau got uplifted about 5 to 6 million years ago. Deposits of calcite on the walls of the canyon indicate the sedimentary rock like shale, sandstone, and limestone. The canyon is a result of erosion and many unconformities are present in this region and the bedrocks are metamorphic n nature found at the bottom of the canyons and occur along with the igneous intrusions called as the Vishnu basement rocks. Thus this suggests that various processes have formed above and below have helped shape the natural landscape and thus a result of erosion and tectonic action the canyon has changed its form over the period of time.
