Flint is a variety of chert (mostly of upper Cretaceous age) that has a conchoidal fracture.Limestone is a sedimentary rock composed of calcium carbonate. It makes up roughly 10% of the total volume of all sedimentary rocks on earth and is unique due to its composition of fossilized shell-producing and coral-building organisms. From a geological perspective, limestone formation occurs either in marine waters or during cave formation.
This shows that sedimentary rocks are formed from sediments. (iii) Limestone is changed into marble. Answer: Igneous and sedimentary rocks change into metamorphic rocks under heat and pressure. This happens in the case of limestone. Limestone, under heat and pressure, changes into marble, which is a metamorphic rock. Inside Our Earth SummaryLimestone is a sedimentary rock composed primarily of calcium carbonate (CaCO3) in the form of the mineral calcite.
