Iron and oxygen account for most of the Earth's mass.
The claim states that iron and oxygen account for most of the Earth's mass. According to the evidence collected, Earth's core is primarily composed of an iron-nickel alloy, which constitutes a significant portion of its mass. However, the mantle and crust are primarily composed of silica compounds, including silicon and oxygen. Oxygen is abundant in the crust but combined with silicon as silicon dioxide (SiO2). The data shows iron and oxygen are major components but not alone the majority. Thus, the claim is partially supported, as other elements like silicon also play a significant role in Earth's composition.

Science
Iron and oxygen account for most of the Earth's mass.
While the Earth's core is largely iron, its mantle and crust are composed significantly of silicon and oxygen among other elements. Evidence indicates iron is a leading component in the core but not in the crust where oxygen is primarily bonded with silicon as silicon dioxide. Therefore, while both elements are crucial, the claim that they constitute the majority is oversimplified or lacks the necessary context about silicon's substantial presence.
