Is limestone a rock or mineral.

Rock salt is the name of a sedimentary rock that consists almost entirely of halite, a mineral composed of sodium chloride, NaCl. It forms where large volumes of sea water or salty lake water evaporate from an arid-climate basin -- where there is a replenishing flow of salt water and a restricted input of other water.Rhyolite (/ ˈ r aɪ. ə l aɪ t / RY-ə-lyte) is the most silica-rich of volcanic rocks.It is generally glassy or fine-grained in texture, but may be porphyritic, containing larger mineral crystals (phenocrysts) in an otherwise fine-grained groundmass.The mineral assemblage is predominantly quartz, sanidine, and plagioclase.It is the extrusive equivalent to granite.Water changes the chemical composition and size of minerals in rock, making them less resistant to weathering.
