Locational advantages regarding raw material and water supply.
Explanation
The location of the iron and steel industry is heavily influenced by the availability of raw materials, particularly coal and iron ore. Since these are weight-losing raw materials, the industry is typically located near the sources of these materials or at points of minimum transport cost to ensure economic viability.
Detailed Analysis:
- Raw Material Availability: Pittsburgh enjoys a significant locational advantage due to the local availability of high-grade coal from the Appalachian region. While iron ore is not found locally, it is sourced from the iron mines in Minnesota (such as the Mesabi Range).
- Transportation and Water Supply: The Great Lakes waterway provides a cost-effective shipping route for bringing iron ore from Minnesota. From the Great Lakes, trains transport the ore to Pittsburgh. Furthermore, the region is situated at the confluence of the Ohio, Monongahela, and Allegheny rivers, which provide an abundant water supply essential for the steel manufacturing process (cooling and processing).
- Analysis of Incorrect Options:
- Availability of cheap labour from fishing villages.: Pittsburgh is an inland industrial center, not a coastal fishing hub; thus, labor from fishing villages is not a relevant factor.
- Government tax holidays.: While government policies can influence industry, the primary historical driver for Pittsburgh's dominance was geographical resource endowment, not tax holidays.
- Proximity to the Atlantic Ocean for export.: Pittsburgh is located in Pennsylvania, inland from the Atlantic Ocean. It relies on river and lake transport rather than direct proximity to the Atlantic coast.
Key Takeaway:
The location of the steel industry in Pittsburgh is primarily driven by the proximity to coal fields (Appalachian) and access to water bodies (rivers and Great Lakes connectivity) for transport and processing needs.
