How does atmospheric oxygen affect Earth’s surface through oxidation processes?
Answer and explanation
Correct answer: It participates in chemical reactions involving minerals and organic matter
Oxidation is a chemical process in which oxygen may combine with another substance or help remove electrons from it. At Earth’s surface, oxygen contributes to rusting of minerals, decomposition and combustion of organic matter, and many weathering reactions. Thus option A correctly describes its role. The other choices exaggerate oxygen’s effects: it cannot alter Earth’s orbit, turn dust into the Sun or eliminate all atmospheric carbon dioxide.
