The Full Story
Oxygen is the dominant element in Earth’s crust by mass, accounting for about 46.6 percent. It is abundant because it combines with many other elements to form silicate minerals, oxides, and other compounds. Although silicon is also very common, oxygen is the clear leader in crustal abundance. This abundance is a major reason why rocks and minerals on Earth are often oxygen-rich.
