Green curves show hypothetical Earths with density constant (dashed) and decreasing linearly from center to surface (stippled).]] ~~[[File%3aEarthGravityPREM.jpg]]~~ The '''Preliminary reference Earth model''' (PREM) is a one-dimensional model representing the average [[Earth]] properties as a function of planetary radius. It includes a table of Earth properties, including elastic properties, [[Anelastic_attenuation_factor\|attenuation]], [[density]], [[pressure]], and [[Gravity of Earth\|gravity]], as a function of planetary radius.
