Which Greenhouse Effect and Global Warming term is correctly associated with type or identity: “the fraction of incoming radiation reflected by a surface”, and also with “snow and ice generally have high albedo”?

Correct Answer: Option A — Albedo. Albedo is correct because it is the fraction of incoming radiation reflected by a surface. Albedo is also associated with snow and ice generally have high albedo. A further identifying fact is that Albedo is ice loss exposes darker surfaces that absorb more heat. Another useful fact is that Albedo is associated with the ice-albedo feedback can amplify warming. Why the other options are incorrect: Option B — Paris Agreement: It is an international climate agreement and is associated with adopted in 2015 under the UNFCCC; those are the identifying facts of Paris Agreement. Option C — Carbon dioxide: It is a long-lived greenhouse gas and is associated with released notably by fossil-fuel combustion and deforestation; those are the identifying facts of Carbon dioxide. Option D — Methane: It is a potent short-lived greenhouse gas and is associated with emitted by livestock, wetlands, landfills and fossil-fuel systems; those are the identifying facts of Methane. Exam Takeaway: Link Albedo with “the fraction of incoming radiation reflected by a surface” and “snow and ice generally have high albedo” for quick revision.
