 INTRODUCTION: In this article we are going to briefly discuss about What is a Rock and what are different classifications of Rocks. And we are also going to discuss about Stones in brief. So, lets start the discussion about Rock and Stone. What is a rock? Solid mass of different types of minerals which forms the earth’s crust is known as Rock.   What is stone? Naturally available construction material quarried and extracted from the rock is stone. The properties of stones depend on parent rock. Classification of rocks is done on the basis of:   i.      Geological formation ii.     Physical characteristics iii.    Chemical composition Physical Classification Based on physical properties There are three types of rocks based on physical properties: 1. Stratified Rocks 2. Unstratified Rocks 3. Foliated Rocks Stratified Rocks •           Th...
