Limestone is is a chemically altered sedimentary rock, mostly consisting of calcium carbonate in various forms. The hardness of calcite, a common ingredient, is about 3 on the Mohs scale. A conglomerate often consists of mechanically altered sedimentary rock that has been ground into relatively small pieces while being transported and deposited as sediment by glaciers. Its Mohs hardness varies, depending on the composition of the rock which is mostly a mixture of silicates, calcite, and iron compounds.
