Recorded sources
10 sources for · 0 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that oxygen is the most abundant element in Earth's crust?

Yes. Multiple reference and peer-reviewed sources state directly that oxygen is the most abundant element in Earth's crust, and a LibreTexts table gives oxygen 46.1% versus silicon's 28.2%.
