What type of grains is igneous rock made from? Whereas sedimentary rocks are produced by processes operating mainly at Earths surface by the disintegration of mostly older igneous rocks, igneousand metamorphicrocks are formed by internal processes that cannot be directly observed and that necessitate the use of physical-chemical arguments to deduce their origins.
