Final answer:
Industrialization in the United States was enabled by high yields in farming, abundant natural resources, a vast territory, and the influx of immigrant workers.
Step-by-step explanation:
Industrialization in the United States was enabled by several conditions. Firstly, high yields in farming created a workforce and consumer market.
Secondly, the abundance of natural resources and a vast territory allowed for expansion and the development of railroads to connect resources to manufacturing locations.
Finally, the influx of immigrant workers in the latter half of the nineteenth century helped meet the labor demands of industrialization.
