Minerals!
Conglomerate and sandstone are rocks made from rounded grains. Conglomerate consists of larger, rounded gravel-sized particles cemented together, while sandstone is composed of smaller, rounded sand-sized grains cemented together.
Rocks are composed of differing combinations of thousands of naturally occurring minerals--or pieces of other rock particles cemented together--or in some cases, lithified organic matter.All rocks are composed of some form of minerals. The exact type of rock and their specific appearance is determined by the elements that are combined with these minerals.
Sedimentary rocks composed of older rocks are called "conglomerate" or "breccia." These rocks form when fragments of older rocks are compacted and cemented together to create a new rock.
