What three elements make up most of the Earth's crust?
Answer (2)
The three most abundant elements that make up the Earth's crust are oxygen, silicon, and aluminum. Oxygen constitutes 46.6% by weight of the Earth's crust, making it the most abundant element. Silicon follows with 27.7% by weight, and aluminum comes in third, comprising 8.1% of the Earth's crust by weight. These three elements dominate the composition of the Earth's crust and form the basis of most minerals found in this outermost layer.
The three primary elements that make up most of the Earth's crust are oxygen, silicon, and aluminum, constituting significant proportions by weight. Oxygen is the most abundant, followed by silicon and aluminum. These elements are foundational in the formation of various minerals that are prevalent in the crust.
