Rocks and Minerals
Geology is similar to other sciences; it has some basic concepts and everything else is built off of those. In this case, geology's basic concepts are mineralogy (the study of minerals) and petrology (the study of rocks). Once understanding the basics of rocks you can move on to greater concepts like maps, geological structures, and how different rocks influence the landscape.
Here we start with an overview of minerals as well as some of the more interesting information about minerals. Once the main concepts are understood there, rocks become a little easier to explain.
