What Is The Difference Between Limestone & Sandstone?

How Limestone and Sandstone Appear Many sedimentary rocks, including sandstone, display a visible stratification into layers. This visual cue can help determine how a rock came to be primarily based at the size and intensity of each layer. Limestone does not have the stratification pattern that sandstone does.
