Rocks are usually composed of minerals, which are naturally occurring inorganic solids with a specific chemical composition and crystal structure. These minerals are formed through various geological processes such as cooling and solidification of molten rock or precipitation from mineral-rich solutions. Additionally, rocks may also contain organic materials, such as fossils or plant remains.
