Earth's Rocks and FossilsBook - 2008
People today can never know exactly what was happening on Earth many millions of years ago, but rocks and fossils have helped scientists learn a great deal. From rocks that have been carved by erosion to skeletons of early humans, rocks and fossils help show us the ways Earth has changed-and what is in store for the future.
