Rock , in geology , naturally occurring and coherent aggregate of one or more minerals. Such aggregates constitute the basic unit of which the solid Earth is composed and typically form recognizable and mappable volumes. Rocks are commonly divided into three major classes according to the processes that resulted in their formation. These classes are 1 igneous rocks, which have solidified from molten material called magma; 2 sedimentary rocks, those consisting of fragments derived from preexisting rocks or of materials precipitated from solutions; and 3 metamorphic rocks, which have been derived from either igneous or sedimentary rocks under conditions that caused changes in mineralogical composition , texture, and internal structure.
