All of the above options are valid reasons why scientists think the Grand Canyon was once covered by an ocean. The sedimentary rock layers found in the canyon were formed under the sea, and seepage of seawater through the canyon floor has been observed. Additionally, the Grand Canyon is located in an area that likely experienced flooding from coastlines, and it would take the strength of an ocean to erode the rock formations found in the canyon.
