What explanation can be given to explain why the rock layers in the Grand Canyon are different thicknesses?
What explanation can be given to explain why the rock layers in the Grand Canyon are different thicknesses? The erosion patterns and thickness of different layers can reveal the climate during different years. A series of very dry years will have very thin layers of rock, when little erosion took place. The overall pattern of erosion and layering reveals the rate of water flow, from both the river and rain, through a canyon.
Why are the rock layers in the Grand Canyon different but yet most of them are a red color?
The vivid colors of many of these layers are due mainly to small amounts of various minerals. Most contain iron, which imparts subtle shades of red, yellow, and green to the canyon walls. Climate plays an important role in the appearance of the canyon.
Why does there appear to be layers of stripes on the walls of the Grand Canyon?
The Colorado River wears away soil, rock, and other materials, making the Grand Canyon deeper every day. The Grand Canyon is striped with colors . The stripes are layers of sediment that stacked on top of each other over many years . Each layer helps us learn how Earth has changed over time .
Why is each layer of the Grand Canyon like a time capsule?
Each geological rock layer of the Grand Canyon is a piece of the puzzle of the history of the Earth. Each layer contains clues into what kind of environment was present when the layer was being deposited. As well as the plants and animals that were living during this chapter of time.
