Which Greenhouse Effect and Global Warming term is correctly associated with major source or process: “forests, soils and oceans can function as sinks”, and also with “reduces the fraction of emissions remaining in the atmosphere”?

Correct Answer: Option B — Carbon sink. Carbon sink is correct because it is forests, soils and oceans can function as sinks. Carbon sink is also associated with reduces the fraction of emissions remaining in the atmosphere. 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 A — Albedo: It is snow and ice generally have high albedo and is associated with ice loss exposes darker surfaces that absorb more heat. Option C — Paris Agreement: It is adopted in 2015 under the UNFCCC and is associated with aims to strengthen the global response to climate change. Option D — Carbon dioxide: It is released notably by fossil-fuel combustion and deforestation and is associated with the largest contributor to human-caused long-term warming. Exam Takeaway: Link Carbon sink with “forests, soils and oceans can function as sinks” and “reduces the fraction of emissions remaining in the atmosphere” for quick revision.
