Answer:
Mineral industry
Explanation:
The most important industry in the American industrial development process is the mineral industry. In industrialization in general, the use of energy and mineral resources is essential.
The U.S. has a large diversity of mineral deposits, such as coal and iron, which are abundant. However, there is a dependence on petroleum due to the decrease in oil reserves and other minerals, making it the largest importer of minerals in the world.
We can see this because the U.S. is the nation that most consumes these resources. The proof of this is the American's cars, with their majority having powerful engines of 8, 10, and 12 cylinders, which consume much fuel.
