The land we walk on is made up of many large plates floating on the Earth's mantle. The slow movement of these plates generates earthquakes and creates continental landforms. The location and characteristics of these landforms determine weather patterns. The mineral specimens displayed in this book, Surfaces appear hard and timeless, but they are also malleable. The content introduces the basis of crystal formation and the large-scale geological forces that shape the Earth. Among them, there are four processes directly responsible for the formation of the basic crystals of all minerals: magmatism, solution precipitation, chemical metamorphism, and crystallization. Granite, sandstone, limestone and marble are the most common products. When the conditions of pressure, heat, and chemical balance are just right (or, rather, just wrong), these same geological forces produce rare voids and veins of large clear, colorful crystals that satisfy our visual senses. These processes are the basis for mineral formation and systematically classify the crystal shape, structure, color and texture of minerals, and the processes by which these minerals are formed are closely related to the large-scale forces that are changing the face of the earth.
