such a place as the Grand Canyon. Some believe that it is the sudden rock slides that have caused most of the canyon to be developed rather than every day flow of the river. The debris from the rock slide falls into the river and is carried down stream. The debris moving down stream eats away at the banks and the bed of the river.
             Sixty five million years ago the surface of the Grand Canyon was level. The area of the Grand Canyon bulged upwards from internal pressure. The geological term for this is upwraping; this process is still going on today. As the plateau gradually rose, shallow rivers that ran across the area of the canyon began to flow more swiftly.
             Over time fourteen layers of rock have been eroded away. Layers were largely worn away over the course of millions of years. The layers of rock that are showing to day are two billion years old. Every layer of rock that is eroded away brings us to a new era in the history of the world. Geologists are able to study fossils and stones from millions and billions of years past, with out the hassle of having to dig.
             The erosion of the canon has slowed down tremendously because it has finally reached down to granite. The granite is so hard that the amount of force there used to be cannot erode away like it did in the past. Another reason the canyon is not eroding as much is due to the weather patterns that we face in today's environment there are very few instances where the c
