Final answer:
Germany obtained iron ore from the Ruhr valley and imported from Sweden and controlled Norway's iron ore resources during World War II.
Step-by-step explanation:
Germany's iron ore came from several sources. One important source was the Ruhr valley, located near the border with France.
This region had extensive coal deposits, which played a vital role in the growth of German industry.
The coal was used in the production of steel, and the iron ore needed for steel production was imported from Sweden.
Moreover, during World War II, Germany invaded Norway to control its iron ore resources and ensure a steady supply for weapon manufacturing.
