In toltal one would see 9 distinctive layers that give us evidence to how and what was going on millions of years ago. The first layer of sediment dating back 250 mil years ago existed during a time where the area was submerged in water. This is evident by its Kaibab limestone

The Grand Canyon was once a part of a continental collision about 1.7 billion years ago when volcanic islands collided in the south west of America‚ where the North American plate is now. Mountain building occurred about 75 million years ago when the uplift of almost 2 miles in the region‚ (called a Laramide orogeny event) started and created the Colorado Plateau. The rocks in the Grand Canyon were igneous or sedimentary rocks before the collision of tectonic plates. The collision pushed the plates
