The volume is part of a national series of seven Teacher-Friendly Guides to regional Earth science, covering all 50 states. This Teacher-Friendly Guide is intended to fill this need for teachers. Further, these resources are not necessarily “teacher-friendly,” or written with an eye toward the kind of information and graphics that a secondary school teacher might need in their classroom. While a number of reasonably good resources exist for individual states, these do not take enough geographic scope into account to show how, say, the coals of Illinois are related to the Late Ordovician marine sedimentary rocks of southwestern Ohio, or why fossil fuels are found in some states and iron mining occurs in other nearby states. Nationally distributed textbooks make few references specifically to the Midwest region. Earth science educators at the Paleontological Research Institution, in working with teachers, have noted that no single source for educators exists that attempts to make sense of the disparate local features of the Midwestern United States in terms of a basic sequence of historical events and processes. These processes link widely separated sequences in a common history. ![]() ![]() The distribution of rocks and landforms can be explained by processes that shape areas covering thousands of kilometers, such as the volcanism, mountain building, and sedimentary basins that accompany converging plates. What is not possible from only one location is making sense of why this particular sequence of events took place when and where it did, particularly relative to sequences in other places around it. In this sense, Earth science is a subject to be explored in one’s own neighborhood, examining the detailed sequence of rocks for the history that has gone on under our feet. No two places share exactly the same sequence of events that led to the way they are today. Preface Earth science is an inherently local subject. ![]()
