Earth: Inside and Out

Earth: Inside and Out explores the ways in which our dynamic planet evolved, and the processes and systems that continue to shape it. Though the geologic record is incredibly ancient, it has only been studied intensely since the end of the 19th century. Since then, research in fields such as geologic time, plate tectonics, climate change, exploration of the deep-sea floor, and the inner earth have vastly increased our understanding of geological processes.
