Describe where metals come from and give one example of how metals are used based on their physical properties
Metals come from the Earth's crust. They are naturally occurring elements that are found in various forms such as ores, minerals, and rocks. The process of extracting metals from these sources is called mining or metallurgy. Metal ores are often melted or chemically treated to obtain the desired metal in a pure form.
One example of how metals are used based on their physical properties is aluminum. Aluminum is a lightweight and corrosion-resistant metal. Due to its low density and excellent strength, it is widely used in the production of aircraft, automobiles, and bicycles. Its properties make it an ideal material for reducing the weight while maintaining structural integrity in these applications. Additionally, aluminum is also used in packaging materials, electrical wiring, and construction materials due to its malleability and conductivity.
