Why is monitoring trace gases in atmospheric composition essential in modern climatology?
Answer and explanation
Correct answer: Because small changes can affect radiation balance and atmospheric chemistry
Trace gases occur in small concentrations, but their effects need not be small. Gases such as carbon dioxide, methane and ozone absorb radiation or participate in chemical reactions, thereby influencing warming, cooling and air quality. Continuous monitoring reveals trends, sources and feedbacks that models must represent. Option A is correct; the other choices wrongly claim that trace gases dominate the atmosphere, remain constant or occur underground.
