<h3>What is a Rock ?</h3>
A rock is a dense mass of mineral grains that have grown or been cemented together over time. There are big rocks and little rocks. Pebbles are little rocks. One or more minerals can be found in every rock.

- Among the physical characteristics of rocks are density, porosity, and permeability. Elastic modulus, Poisson's ratio, and rock strength are the primary characteristics of rocks in terms of mechanics.
