weathering, erosion, and deposition contribute to the formation of rock layers in the Grand Canyon?
the colorado river, which runs through the canyon was respnsible for eroding and deepening it through processes like attrition, abrasion, friction. these processes eroded sediments away and deposited them at the meander corners and at the mouth of the river. weathering is the degradations of rocks in situ, that is, in an immobile state, without erosion. chemical and mechanical weathering are controlled by fluctuations in temperature and precipitation. all these processes are explained in most geography text books.
You have a good one in textbook. An alternate source would be the Grand Canyon website.
