ответ:

the main consequence of the industrial revolution was industrialization - the transition from a predominantly agrarian economy to industrial production, which resulted in the transformation of the agrarian society into an industrial one.

the industrial revolution did not take place in different countries at the same time, but it is generally believed that the period when these changes took place begins from the second half of the 18th century and continues throughout the 19th century. a characteristic feature of the industrial revolution is the rapid growth of productive forces on the basis of a large machine industry, as well as the establishment of capitalism as the dominant world economic system.

the industrial revolution coincided not only with the beginning of the mass use of machines, but also with a change in the whole structure of society. it was accompanied by a sharp increase in labor productivity, rapid urbanization, the beginning of rapid economic growth (before that, economic growth, as a rule, was noticeable only at the scale of centuries) and an increase in the living standard of the population.

having begun in great britain, the industrial revolution, having passed through the countries of europe and the usa, allowed only 3-5 generations to pass from an agrarian society (where the majority of the population lived in subsistence) to an industrial one.
