Nether gold ore is a variant of gold ore found only in the Nether. Nether gold ore generates in the Nether in the form of ore blobs. Nether gold ore attempts to replace netherrack 10 times per chunk in blobs of size 0–16, from levels 10 to 117, in all Nether biomes. In Java Edition, in basalt deltas, nether gold ore attempts to generate 20 times …

Where precession, in terms of the angles used in this section, represents a change in (theta), nutation is associated with a change in the tilt angle (phi). It comes about in several cases, most commonly due to the action of a second force, and often results in a periodic motion (hence the name nutation, 'nodding'). One example is the ...
