why were iron tools more difficult to obtain than copper ones ?
Copper melts at a lower temperature than iron. Therefore, in order to remove it from the ore in which it is found, and in order to work it, a hotter fire is needed to for iron than for copper. Making a fire hot enough to extract and work iron is more difficult, so iron tools were more difficult to obtain than copper tools.
