What two resources make the 2nd wave of industrialism the greatest the world has ever seen?

Answer :

Is this about the British industrialization?
if so then I’d say that the two resources that were very important during that period were textiles. Basically cotton and wool. If we’re talking about transportation resources then river canals and railway systems. If this isn’t even about the British Industrial period then i’m sorry. Be more specific.
Iron and steel, as well as railroads and coal
