These are declination (D), inclination (I), horizontal intensity (H), the north (X) and east (Y) components of the horizontal intensity, vertical intensity (Z), and total intensity (F). The parameters describing the direction of the magnetic field are declination (D) and inclination (I).
WebIn a sense, yes. The Earth is composed of layers having different chemical compositions and different physical properties.
