An overview of the history of physical, chemical and biologic changes that have taken place on Earth since its formation 4.6 billion years ago. A major emphasis in the course is on the tools and techniques that are used to read and interpret this history using fossils and physical features in the rock. Laboratory and field exercises illustrate events in Earth's history and provide students with opportunities to engage in geologic inquiry. Writing in the discipline is emphasized through laboratory reports, field trip reports and research papers. The course requires multiple Saturday field trips to examine fossils and rocks for practical experience on interpreting Earth's history. Offered Spring only.
