what is the difference between a hard rock and a soft rock

13-6-2010Hardness is a property of minerals, not rocks. As rocks are composed of one or more minerals, geologists rarely talk about rocks as being hard or soft. In general, hard rock is comprised of igneous and metamorphic rocks (granite, basalt, gneiss, schist etc), and soft rock is comprised of various sedimentary rocks (shale, limestone etc.).

Comparison of Sandstone and Limestone

Sandstone is a sedimentary rock composed mainly of sand-sized minerals or rock grains. Sandstone is hard as compared to limestone and less corroded by rainwater, so we find it near the rivers, lakes and in desert areas. Sandstone is preferred for the use in metallic road construction because its hardness, compressive strength is more.
