Which Greenhouse Effect and Global Warming term is correctly associated with type or identity: “a reservoir that absorbs more carbon than it releases”, and also with “forests, soils and oceans can function as sinks”?

Correct Answer: Option A — Carbon sink. Carbon sink is correct because it is a reservoir that absorbs more carbon than it releases. Carbon sink is also associated with forests, soils and oceans can function as sinks. A further identifying fact is that Carbon sink is reduces the fraction of emissions remaining in the atmosphere. Another useful fact is that Carbon sink is associated with a sink can weaken if ecosystems are degraded. Why the other options are incorrect: Option B — Albedo: It is the fraction of incoming radiation reflected by a surface and is associated with snow and ice generally have high albedo. Option C — Paris Agreement: It is an international climate agreement and is associated with adopted in 2015 under the UNFCCC. Option D — Carbon dioxide: It is a long-lived greenhouse gas and is associated with released notably by fossil-fuel combustion and deforestation. Exam Takeaway: Link Carbon sink with “a reservoir that absorbs more carbon than it releases” and “forests, soils and oceans can function as sinks” for quick revision.
