Answer:
Railroads became a major industry, stimulating other heavy industries such as iron and steel production. These advances in travel and transport helped drive settlement in the western regions of North America and were integral to the nation's industrialization.
Step-by-step explanation:
An early landmark moment in the Industrial Revolution came near the end of the eighteenth century, when Samuel Slater brought new manufacturing technologies from Britain to the United States and founded the first U.S. cotton mill in Beverly, Massachusetts. Slater’s Mill in Pawtucket, Rhode Island, like many of the mills and factories that sprang up in the next few decades, was powered by water, which confined industrial development to the northeast at first. The concentration of industry in the Northeast also facilitated the development of transportation systems such as railroads and canals, which encouraged commerce and trade.
The technological innovation that would come to mark the United States in the nineteenth century began to show itself with Robert Fulton’s establishment of steamboat service on the Hudson River, Samuel F. B. Morse’s invention of the telegraph, and Elias Howe’s invention of the sewing machine, all before the Civil War. Following the Civil War, industrialization in the United States increased at a breakneck pace. This period, encompassing most of the second half of the nineteenth century, has been called the Second Industrial Revolution or the American Industrial Revolution. Over the first half of the century, the country expanded greatly, and the new territory was rich in natural resources. Completing the first transcontinental railroad in 1869 was a major milestone, making it easier to transport people, raw materials, and products. The United States also had vast human resources: between 1860 and 1900, fourteen million immigrants came to the country, providing workers for an array of industries.
The American industrialists overseeing this expansion were ready to take risks to make their businesses successful. Andrew Carnegie established the first steel mills in the U.S. to use the British “Bessemer process” for mass producing steel, becoming a titan of the steel industry in the process. He acquired business interests in the mines that produced the raw material for steel, the mills and ovens that created the final product and the railroads and shipping lines that transported the goods, thus controlling every aspect f the steelmaking process.
