Astronaut photographs and satellite images have revealed the exquisite beauty of Earth, a planet washed in water and surrounded by a thin atmosphere with swirling white clouds. Since the 1960s, however, we have seen our planet as it really is, a tiny blue sphere suspended in the blackness of empty space, as this photograph of the International Space Station hovering over EarthвЂ™s cloud-covered oceans illustrates so dramatically. Our perspective for observing and understanding Earth and its changes was very limited-at best, a vantage point on a high hill or mountaintop. But from our beginnings, we have been able to perceive only our immediate landscape, usually only a few square kilometers.

Understanding our environment has always been essential. Image provided by SeaWiFS Project, NASA/Goddard Space Flight Center and ORBIMAGEДЇor hundreds of thousands of years, humans have learned to survive by adapting to the natural rhythms and cycles of the planet on which we live. This is what makes geology so fascinating- it is the study of changes that affect every aspect of our lives. Our present is affected by our past and the present will shape the future. Finally, you will see that geology is also a historical science. Here you will be introduced to the great planetary systemsвЂ“plate tectonics and the hydrologic system. Forces in the tectonic system can contort and deform it, and we will guide you through a basic understanding of the resulting structures. But even after a rock body is formed, it is not static. In this part of the book, you will be introduced to each major system, to the energy that drives the flow of matter and makes Earth truly dynamic, and to rocks and minerals-the materials that this energy acts upon. These systems are the mechanism by which energy and matter interact to create the infinite array of landforms and landscapes, structures and stones. Earth is a major system of energy and matter with many interconnected and interrelated subsystems. Planet Earth Geologic Systems Minerals Igneous Rocks Sedimentary Rocks Metamorphic Rocks Structure of Rock Bodies Geologic Time We begin this study of planet Earth with an examination of EarthвЂ™s composition and take you on a brief tour across its surface and into its deepest interior.
