Look at the layers in the sedimentary rock in the Grand Canyon. QUESTIONS 1. Show with your finger which sediment of rock is the oldest. The lowest sediment/ layer of rock they can see in the photo. 2. Show where you can find soil, in the picture. Above the top most sediment, where the plants grow. Sedimentary rocks are also eroded and broken down into grains of sand again. The sedimentary rock in the Grand Canyon formed a very long time ago. The layers of sediment were once deposited in warm shallow seas and over millions of years they compacted to form rock. The wind and rain have eroded it until it looks like this. Look at the diagram below which summarizes how sedimentary rock is formed, mostly under the sea or lakes and rivers. 132 Earth and Beyond 6
