Introducing Geology: A guide to the world of rocks PDF

Our world is made of rock. Those who live in a landscape where rock outcrops are obvious will have wondered about the kind of rock they are looking at and how they came to be where they are now. Graham Park explains in simple terms what geology can tell us about the world. Many objects of great beauty and which excite our curiosity, such as crystals or fossils are to be found by examining rocks. Those searching for and examining such objects gain much more by knowing how they originated; whilst fossils, interesting in themselves, tell us, from their context in geological time, of biological evolution and these clues give an insight into the origins of life on earth.
