How Fossils Work - HowStuffWorks

The majority of the rocks found in and on the Earth''s crust are sedimentary rocks. They form when sediments, like silt and sand, collect and harden. Over the course of millions of years, this process results in thick layers of sedimentary rock. In some parts of the world, such as the Grand Canyon, you can see these layers.
