How did mass production change the way products were created?

 processes attain high rates of output at low unit cost, with lower costs expected as volume rises. Mass production methods are based on two general principles: (1) the division and specialization of human labor and (2) the use of tools, machinery, and other equipment, usually automated, in the production of standard, interchangeable parts and products. The use of modern methods of mass production has brought such improvements in the cost, quality, quantity, and variety of goods available that the largest global population in history is now sustained at the highest general standard of living.hope this helps :)

I'm pretty sure that's called a volcano
