For a fire is kindled in My anger, And shall burn to the lowest hell; It shall consume the earth with her increase, And set on fire the foundations of the mountains.
(Deuteronomy 32:22) NKJV
It’s very useful to know the volume of material in the Earth’s crust and mantle, but before we move on it’s also worthwhile to note that the Earth’s crust and mantle have several Biblical synonyms.
Crust and Mantle, Synonyms
Usage | Hebrew | Transliteration | Scripture |
bottoms of the mountains | לְקִצְבֵ֤י הָרִים֙ | qetseb har | Jonah 2:6 |
foundations of the hills | וּמוֹסְדֵ֣י הָרִ֣ים | mowcadah har | Psalms 18:7 |
foundations of the mountains | וּמוֹסְדֵ֣י הָרִ֣ים | mowcadah har | Deut. 32:22 |
foundations of the world | מוֹסְד֪וֹת תֵּ֫בֵ֥ל | mowcadah tebel | Psalms 18:15 |
This isn’t a particularly complex problem. We can estimate the volume of material that’s in the earth’s mantle at the present time by using the boundaries of the regions of the earth that we get from seismological data.
If we assume that this volume of material was a hollow sphere, of which the inner radius is the same as the present day earth surface, then we can calculate the radius of the earth on the 3rd day. There is a useful tool that helps with these calculations which may be found here.
Earth, Present Day (values)
Earth, Present Day | Approx. radius (km) | v | Approx. volume (m3) |
Volumetric radius | 6,371 | v1 | 1.08E+12 |
Inner surface of mantle | 4,100 | v2 | 2.89E+11 |
Mantle material (v1-v2) | v3 | 7.95E+11 | |
3rd day total volume (v1+v3) | 7,653 | v4 | 1.88E+12 |
Volume of Earth’s Mantle
Factor | Symbol | Radius | Volume |
Earth total volume | p | 6,371 km | 1.08E+12 m3 |
Volume of core and great gulf | g | 4,100 km | 2.89E+11 m3 |
Volume of mantle material | p-g (m) | 7.95E+11 m3 |

The total volume of present day Earth is 1.08E+12 m3
The volume of material in the crust and mantle is found by subtracting the volume of a sphere of radius 4,100 km from the volume of a sphere of radius 6,371 km
The area between the lower mantle and the core is open space, the great gulf. There’s no inner and outer core. That’s just a contrivance of popular science (SciPop) to make it seem like they know what they’re talking about, and they want to believe (and they want you to believe) that there’s no hell. The core is hell. This isn’t a euphemism.
