# How to Calculate and Solve for Geoid Height Anomaly for Crustal and Mantle Densities | Gravity

The image above represents geoid height anomaly for crustal and mantle densities. To calculate geoid height anomaly for crustal and mantle densities, one essential parameter is needed and this parameter is height (h1).

The formula for calculating geoid height anomaly for crustal and mantle densities:

Î”h â‰ƒ 6h1Â (0.7 + 0.066h1)

Where:

Î”h = Geoid Height Anomaly for Crustal and Mantle Densities
h1Â = Height

Let’s solve an example;
Find the geoid height anomaly for crustal and mantle densities when the height is 12.

This implies that;

h1 = Height = 12

Î”h â‰ƒ 6h1Â (0.7 + 0.066h1)
Î”h â‰ƒ 6(12) (0.7 + 0.066(12))
That is, Î”h â‰ƒ (72) (0.7 + (0.792))
Î”h â‰ƒ (72) (1.492)
Î”h â‰ƒ 107.424

Therefore, theÂ geoid height anomaly for crustal and mantle densities isÂ 107.424 m.
