A. Oxygen
B. Hydrogen
C. Carbon Dioxide
D. Silicon
Check Answer
The correct answer is A) Oxygen.
The most abundant element in the Earth’s crust is Oxygen. Oxygen makes up about 46.6% of the Earth’s crust by weight, making it the most abundant element on Earth. It is a highly reactive element and it is never found as a pure element, but in compounds such as water, carbon dioxide, and silicates.
Oxygen is an essential element for all known forms of life, it is also key component of the atmosphere, providing the oxygen that living organisms need to survive. The Earth’s crust contains about 49% of oxygen in the form of oxides, mainly silicates and oxides of aluminum, iron and other metals. The Earth’s crustal rocks and minerals also contain a number of other elements, such as silicon, aluminum, iron, calcium, sodium, and potassium.
