The document contains information about different types of rocks presented across 12 cards. It discusses the classification of rocks by their textures, how they are formed from minerals and sediments, and key characteristics. Igneous rocks such as granite form from cooling magma and volcanism. Sedimentary rocks like limestone and sandstone form through compaction and cementation of sediments. Metamorphic rocks change form due to heat and pressure acting on existing rocks.
