<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.
- According to how they were formed, rocks are categorised by geologists (those who study rocks and minerals).
- 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.
