Earth's gravity according to the preliminary reference earth model (PREM).
Comparison to approximations using constant and linear density for Earth's
The density of the Earth is 5.513 g/cm3. This is an average of all of the material
on the planet. Water is much less dense than iron, hence an average is n.

CALCULATING THE MASS AND DENSITY OF EARTH. Kepler's Third Law (
Newton's Form): P. 2 a. 3. = 4π. 2. MG. The period of the moon's orbit is 27.32
"They divide the mass of the Earth by the volume, which gives the average
density of the material in the earth as 3.2 ounces per cubic inch (5.5 g/cm<sup>3</sup>)." 5.5
The overall density of the earth is actually fairly easy to calculate: if density
equals mass divided by volume, and we can find the mass and volume of the
What is the best estimate of the densities of the various layers of the Earth?
Estimates vary, but some approximate values should be as follows (in grams per
The planet which closely resembles the Earth in its mass, density and volume is
Venus. Mercury has almost the same density as earth but is relatively smaller in ...
This narrow stratum as compared with the diameter of the Earth is but one half
the ... Modeling the density of the center of the Earth yields densities of about 14 ...
Density is the ratio of mass to volume. Use the given mass of the Earth and
calculate its volume from the radius and the equation for the volume of a sphere.
