Iron is a strong, malleable metal that is one of the most abundant elements on Earth. It is primarily extracted from iron ore through a process called smelting, where it is heated with carbon to remove impurities. Iron is widely used in construction, manufacturing, and various tools due to its durability and strength. Steel is an alloy made primarily from iron and a small amount of carbon. This combination enhances its strength and resistance to corrosion, making it ideal for a variety of applications, including buildings, bridges, and vehicles. The versatility of steel has made it a fundamental material in modern industry and infrastructure.
