Metals primarily come from the Earth's crust, where they are found in ore deposits. These ores are mined and processed to extract the metals, which can then be refined and shaped into various forms. For example, aluminum is derived from bauxite ore.
One notable use of metals based on their physical properties is in construction. Steel, which is an alloy of iron, is valued for its high tensile strength and durability, making it an ideal material for building structures like bridges and skyscrapers that must withstand significant forces and loads.
