which one of the following is an important center of iron and steel industry in USA?
Answers
Answer:
(US steel) is the correct ✅ answer
Answer:
Once USA was the highest producer of iron and steel but now its rank is third in the world, next to China and Japan. In the US first iron and steel plant was established in 1629 at Massachusetts. During last 380 years or so the US steel industry has undergone through several changes. This change has not only occurred in growth and production pattern but also in localisation pattern. The major iron and steel regions in the USA are as follows:
Explanation:
The northern Appalachian region of western Pennsylvania and eastern Ohio is the most important of all the regions. This district contains approximately 42.5 percent of the country's blast furnace capacity, and its centre, Pittsburgh, is the world's second largest steel industry centre. The mills in this region are almost entirely concentrated in the narrow valleys of the Ohio River's headwater streams, including the Ohio itself.
Only the Middle Atlantic region (New York, Philadelphia, and Baltimore, for example) is significant on the Atlantic Seaboard. The primary advantage of this region is its location, both in relation to the tidewater and in proximity to the major industrial centres of the region.
Its location near the heart of the Atlantic Seaboard's great manufacturing region, the region with the densest population and the most intense industrial development in North America, is by far the most spectacular.
Huge reserves of these raw materials are discovered in closer proximity in the Southern Appalachians, in Alabama, than anywhere else in North America, if not the globe. While the ore is low grade and requires shaft mining, because much of the stone is lime, the ore is self-fluxing.
The region, however, lacks large industrial centres in the surrounding area, resulting in a significant amount of surplus pig iron that is exported to the North.
