When mining for resources, there are "levels" that each resource appear. For example, Diamonds appear at levels 11-16 (roughly).
Can someone list all of the ranges for each major resource? (Coal, Iron, Gold, Redstone, Diamond, Emerald, etc)
And for some of the more common resources, like Coal or Iron, is there a range where they are more commonly found? I.e. If Diamond only appears at level 11-16, is it likely they occur more often at level 13 for example?
