Greenhouse Effect and Global Warming Questions and Answers

Correct Answer: Option D — Paris Agreement. Paris Agreement is correct because it is countries submit nationally determined contributions. Paris Agreement is also associated with an international climate agreement. A further identifying fact is that Paris Agreement is aims to strengthen the global response to climate change. Another useful fact is that Paris Agreement is associated with countries submit nationally determined contributions. Why the other options are incorrect: Option A — Carbon dioxide: It is forests and oceans absorb part of its emissions and is associated with a long-lived greenhouse gas; those are the identifying facts of Carbon dioxide. Option B — Methane: It is it is the main component of natural gas and is associated with a potent short-lived greenhouse gas; those are the identifying facts of Methane.

Option D — Nitrous oxide: It is also contributes to stratospheric ozone depletion and is associated with it should not be confused with nitrogen dioxide. Exam Takeaway: Link Paris Agreement with “aims to strengthen the global response to climate change” and “countries submit nationally determined contributions” for quick revision.

Correct Answer: Option B — Paris Agreement. Paris Agreement is correct because it is adopted in 2015 under the UNFCCC. Paris Agreement is also associated with aims to strengthen the global response to climate change. A further identifying fact is that Paris Agreement is aims to strengthen the global response to climate change. Another useful fact is that Paris Agreement is associated with countries submit nationally determined contributions. Why the other options are incorrect: Option A — 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. Option C — Methane: It is emitted by livestock, wetlands, landfills and fossil-fuel systems and is associated with warms more strongly per molecule than carbon dioxide over shorter periods. Option D — Nitrous oxide: It is strongly linked to agricultural soils and nitrogen fertilisers and is associated with also contributes to stratospheric ozone depletion. Exam Takeaway: Link Paris Agreement with “adopted in 2015 under the UNFCCC” and “aims to strengthen the global response to climate change” for quick revision.

Correct Answer: Option D — Albedo. Albedo is correct because it is the ice-albedo feedback can amplify warming. Albedo is also associated with the fraction of incoming radiation reflected by a surface. 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 A — Paris Agreement: It is countries submit nationally determined contributions and is associated with an international climate agreement; those are the identifying facts of Paris Agreement.

Correct Answer: Option D — Carbon sink. Carbon sink is correct because it is a sink can weaken if ecosystems are degraded. Carbon sink is also associated with a reservoir that absorbs more carbon than it releases. 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 the ice-albedo feedback can amplify warming and is associated with the fraction of incoming radiation reflected by a surface.
