Step-by-step explanation:
The United States became a world power after the Industrial Revolution primarily through its economic and military strength. As a result of the Industrial Revolution, American businesses gained a competitive advantage in delivering high-quality products at lower costs. This enabled the United States to expand its reach globally through trade and establish itself as a dominant economic power.
In addition, the United States had access to vast natural resources, such as oil, which further fueled its economic growth. The country's growing population and technological advancements allowed it to build a massive manufacturing capability and become a manufacturing powerhouse.
