tldr; Increased density corresponds with decreased P-wave velocity The P-wave velocity for an isotropic medium is: $$V_p = \sqrt\frac{K+4/3\mu}{\rho}$$ where $K$ is the Bulk Modulus, $\mu$ is the shear modulus, and $\rho$ is the density (https://en.wikipedia.org/wiki/Elastic_modulus, see $M$ the P-wave modulus). Isotropy just means that the strain on ...
