Potential Resource.​

Answer 1

Answer:

potential resource

Explanation:

Answer 2

• In its metallic state, iron is rare in the Earth's crust, limited mainly to deposition by meteorites.
• Iron ores, by contrast, are among the most abundant in the Earth's crust, although extracting usable metal from them requires kilns or furnaces capable of reaching 1,500 °C (2,730 °F) or higher, about 500 °C (900 °F) higher than what is enough to smelt copper.
• Humans started to master that process in Eurasia only about 2000 BCE[not verified in body], and the use of iron tools and weapons began to displace copper alloys, in some regions, only around 1200 BCE. That event is considered the transition from the Bronze Age to the Iron Age.
• In the modern world, iron alloys, such as steel, inox, cast iron and special steels are by far the most common industrial metals, because of their mechanical properties and low cost.
