Describe where metals come from, and give one example of how metals are used based on their physical properties
Metals are naturally occurring elements that are found in the Earth's crust. They originate from various sources, such as volcanic activities, hydrothermal vents, and the gradual cooling and solidification of molten rocks.
One example of the use of metals based on their physical properties is aluminum. Aluminum is a lightweight, ductile, and malleable metal. Due to its low density, it is widely used in the aerospace industry for making aircraft frames, wings, and other components. Its malleability allows it to be easily formed into different shapes, while its ductility enables it to be drawn into thin wires for electrical transmission purposes. Additionally, aluminum is highly corrosion-resistant, making it suitable for applications in marine environments, such as constructing ship hulls and offshore structures.
