Minerals a naturally occurring, homogeneous, inorganic solid substance having a definite composition and crystalline structure. Rocks consist of more than one kind of minerals . Atom the smallest unit of matter that retain the characteristic of an element. Atoms have a compact nucleolus that contain protons (+), neutrons, and electrons. Chemical compounds (of minerals) consist of 2 or more different chemical elements, held together by chemical bonds (ex. carbonate) The chemical characteristics of earth materials reflect the environments how and where they are formed. 3 types of rocks: igneous rocks forms from magma or lava. Sedimentary rocks form from particles called sediment (sand, salt, clay, etc. that are torn off from other rocks. Metamorphic rocks are formed by great heat and/or pressure.
