Course detail: OSH262 - Deep Time: Stories from the Rocks

It is only in relatively recent history that we have come to understand that the earth is immensely older than a few thousand years. By careful studies of rock layering and their fossils and minerals, ancient worlds have emerged out of our seas, forests and deserts. The study of geology has the axiom that "the present is the key to the past." However, the record of the rocks can also tell us something about the future of the planet. In this class we will review some chapters from earth history and examine fossils and rock sample that provide clues to this story.
