In a rock, it rarely contains only one mineral, so most rocks contain a combination of two or more minerals. The presence of these minerals becomes an inorganic substance with a certain chemical composition and atomic structure. Moreover, the number of minerals varies. The discipline that studies the presence of rocks on planet earth is called Petrology, which is an important component of geology. Usually, the presence of these rocks is used by humans for building foundations that are less than 10 meters high. In addition, rocks that have unique colors and textures are often used as decoration on a building. only it must go through the process of lifting to the surface of the earth first. The process of lifting rocks below the earth's surface usually occurs through tectonic processes.
We all know that magma is a hot liquid, so that the ions that make it up will also move freely without being regular. Well, when a volcano erupts, magma will definitely also come out and melt along the earth's surface. If the melted magma is exposed to rainwater, it will definitely experience the crystallization process. In this process, you can imagine it as water that is cooled to ice. The presence of sedimentary rocks has a large number, especially below the earth's surface. When the rock is not exposed to the surface of the earth, especially when there is a lifting process (tectonic), then the rock will be buried even deeper. This crystallized magma can usually be found along volcanoes that have erupted. Well, from this frozen magma, a type of rock will form, namely igneous rock.
