                                                                Why is steel called the backbone of modern industries? Why is steel so widely used for industrial purposes?        

    Answer:

         
    (a) Steel is called the backbone of modern industries because almost everything we use is either made up of steel or is made by using devices and tools made of steel.
    (b) Steel is tough and can easily be shaped, cut or made into wires. The alloys of steel have unusual hardness/ toughness and the ability to resist rusting. That is why/ steel is so widely used for industrial purposes.
