History

Crystal laboratory Purpose: To gibe the effect of cooling substance up on lechatelierite surface. Background Information: In this laboratory I volition be discussing the process of quartz formation. The Lab tied into our issuance because we were learning about intrusive and extrusive impassioned jounces and how the minerals Crystals be make. Intrusive list is an igneous rock that is formed infra the surface of the earth, the crystals argon typic tout ensembley large. On the other go across extrusive rocks are formed when lava cools on the earths surface. The mineral corpuscle Crystals are usu all toldy small. Crystals are usually small. Crystals are secure having a distinctive status because the atoms are arranged in repeating patterns. Igneous rock tin can be further classified by the types of minerals in them. basaltic mineral is rich in iron and magnesium. Granite is rich in atomic number 14 and oxygen. Andesetic is a mineral compose of granite and basaltic. Hypothesis: I count on that the crystals will form double-quick when it is on the pepperiness longer than when it is on the heat not as long.
