Industrial Revolution

What was the most important aspect of the Industrial Revolution?

Coal extraction was the most important part of the Industrial
Revolution, and without it, life today would not be the same. Without the extraction of coal, things like steam engines, machines, iron, and metal devices would not be present and active in modern time. Coal extraction changed the way materials were produced and delivered by powering machines and transportation to efficiently finish the job. Industrial production would still be developing if coal extraction wasn’t used as a tool to help polish and improve the way the systems worked. Agricultural produce was transported to the city or the industries by trains/the railways which are made from iron smelting, that run on steam power, which would not be possible without coal extraction. It’s all a system that connects and at times there are doubts on what started it all, but without coal extraction, most of the major aspects of the Industrial Revolution could not exist.
