The Earth is made of rocks and this poster provides a comprehensive overview of what they are and how they are formed. It begins by explaining that rocks are made of minerals and that each type of rock is the result of a specific mixture of minerals subjected to a clearly defined geological process. The bulk of the poster is divided into three sections, one for each type of rock: igneous, sedimentary and metamorphic. An There are approximately 100 common minerals. Over 60 of them are shown on this poster, making it even more helpful for identification. For even greater help, use Introduction to Minerals with our popular Minerals (see link at left), as it presents a whopping 162 magnificent mineral specimens, all grouped by class. They include almost all of the common minerals and most of the 50 minerals classified as scarce. The others are considered rare to extremely rare.
