how do rocks such as limestone and marble form

How do you recognize limestone and marble? [USGS]

How do you recognize limestone and marble? The main difference between limestone and marble is that limestone is a sedimentary rock, typically composed of calcium carbonate fossils, and marble is a metamorphic rock. Limestone forms when shells, sand, and mud are deposited at the bottom of oceans and lakes and over time solidify into rock.
