Answer 1

the grand canyon was formed by physical weathering such as erosion caused by the colorado river. at the bottom of the canyon is a sandy plain known as "the floor" which includes several creeks and rivers. it is estimated that it took around 6 million years for the grand canyon to reach its current size and shape.
