Which Greenhouse Effect and Global Warming term is correctly associated with type or identity: “a natural atmospheric warming process”, and also with “occurs when gases absorb and re-emit outgoing infrared radiation”?

Correct Answer: Option A — Greenhouse effect. Greenhouse effect is correct because it is a natural atmospheric warming process. Greenhouse effect is also associated with occurs when gases absorb and re-emit outgoing infrared radiation. A further identifying fact is that Greenhouse effect is keeps Earth warm enough for life. Another useful fact is that Greenhouse effect is associated with human emissions strengthen the natural effect. Why the other options are incorrect: Option B — Global warming: It is a long-term rise in Earth's average surface temperature and is associated with driven currently mainly by human greenhouse-gas emissions. Option C — Carbon sink: It is a reservoir that absorbs more carbon than it releases and is associated with forests, soils and oceans can function as sinks. Option D — Albedo: It is the fraction of incoming radiation reflected by a surface and is associated with snow and ice generally have high albedo. Exam Takeaway: Link Greenhouse effect with “a natural atmospheric warming process” and “occurs when gases absorb and re-emit outgoing infrared radiation” for quick revision.
