Which metal is the most abundant on Earth?

Explanation:
Understanding which metal is most abundant in Earth's crust helps distinguish crustal composition from the core: aluminum is the most abundant metal, making up roughly 8% of crustal mass, more than iron, copper, or titanium. Iron is still plentiful, but its major reservoir is the Earth's core and it appears in crustal minerals at lower percentages. Aluminum is widespread in crustal rocks, appearing in minerals such as feldspars and in ores like bauxite, which is why it shows up as the top metal in the crust. So aluminum is the best answer.
