Wicander and Monroe (2016): Historical Geology (8e) There have been several episodes of global cooling throughout Earth’s history, notably at the end of the Precambrian (Proterozoic Eon), at the end of the Ordovician Period, during the late Carboniferous to Permian periods, and in a series of glacial and interglacial episodes during the Pleistocene Epoch.
Final Remarks • We don’t just study geology – we live it • Our standard of living depends on our consumption of natural resources which formed millions of years ago - The way we consume these resources and interact with the environment determines what is going to be available for next generations • Try to put each lecture in this course in the context of how it fits in the whole Earth’s system - This way you will gain a greater appreciation of why geology is so integral in our lives
