All rocks can become other rocks by the processes of erosion  and metamorphism.    An igneous rock may become eroded into its constituent mineral  grains such as â¦ quartz and feldspar, which are transported by wind  and water, eventually settling to form a sedimentary rock.There are 4 main groups that igneous rock is divided into by  chemical content.
