Answer 2

Density refers to the amount of matter in the rocks

Explanation:

• The term "density" refers to the amount of mass per unit of volume.
• An object's average density is equal to its whole mass divided by its total volume.
• An object constructed of a relatively dense material (such as iron) will have less volume than one made of a less dense substance of comparable mass (such as water).
• Density is defined as mass divided by volume  

                           ${\displaystyle \rho ={\frac {m}{V}}}$

• where ${\displaystyle \rho$ stands for density, $m$ for mass, and $V$ for volume.
• Unit for mass is $(Kg)$ ,Unit for Volume is $(m^3)$ ,So the unit for density is$(Kg/m^3)$
• Temperature and pressure affect the density of a substance. For solids and liquids, this variance is often minimal, but for gases, it is significantly bigger.
• When you apply more pressure on an object, it shrinks in volume and so becomes denser. With a few exceptions, increasing the temperature of a substance decreases its density by expanding its volume.
• Due to the decrease in density of the heated fluid, which causes it to rise relative to denser unheated material, heating the bottom of a fluid leads in convection of heat from the bottom to the top in most materials.
