The science of rocks is fascinating! This rock-solid series looks at the characteristics of different types of rocks-igneous, sedimentary, and metamorphic-describing everything from their mineral components to their color, and whether or not they contain fossils.
Heat, pressure, and stress can change some igneous or sedimentary rocks into other kinds of rocks.
Metamorphic rocks are often used as materials for floors, roofs, and countertops because of their beauty. Discover the process that turns limestone into marble, shale into slate, and granite into gneiss.
