summarize what have learned in Chapter 5 Rock Forming Minerals topic, specifically the topic of Crystallography. (100 words)

In Chapter 5, we learned about Rock Forming Minerals, focusing on Crystallography. This topic delves into the study of crystal structures and their formation. We learned that minerals form crystals due to the orderly and repetitive arrangement of atoms. The shape and size of these crystals are influenced by the conditions under which they form. We also explored the seven crystal systems, each defined by their unique symmetry and the angles between their faces. These systems include cubic, tetragonal, orthorhombic, hexagonal, trigonal, monoclinic, and triclinic. Understanding these systems helps in identifying and classifying minerals.
