Crystals, if present, are too small to be seen with the unaided eye.. Types of Rocks. Rock: an aggregate of one or more minerals. Igneous Rocks: crystallize from a magma. Sedimentary Rocks. Clastic: formed by the erosion of pre-existing rocks. Chemical/Biochemical: precipitated from chemical reactions. 7404. ]. Dr.. Hill. . Gendoet. Hartono. Semester . 7, . 20. 1. 7-2018. 2 SKS . teori.
