  • How Was The Grand Canyon Formed? » Science ABC
    OriginFormationCourseGeologyThe Grand Canyon was not formed by a single event in history, but over the course of millions of years. Scientists and geologists believe that there was no canyon in that area around 35 million years ago. The Colorado River flowed across a vast plain. Around the same time, the Kaibab Plateau started to appear right in the middle of the rivers flow. Since the water couldnt pass over or through the plateau, the rivers course was diverted.See more on scienceabc
