Below are sample questions representative of the exercises included on this worksheet and related 9.120 Feedbacks Among Earth Systems skill assessments:

Problem 1Difficulty: Mastery

Which sentence best explains a positive atmosphere-hydrosphere feedback?

AInitial warming increases evaporation; added atmospheric water vapor traps more heat; the extra heat amplifies the initial warming

BInitial warming increases plant growth; plants remove carbon dioxide; the greenhouse effect weakens

CInitial warming causes one storm; the storm ends without changing the climate driver

DInitial warming increases rock weathering; weathering removes carbon dioxide; the original warming is reduced

Solution & Explanation:The water-vapor sequence links ocean evaporation and atmospheric greenhouse warming in a loop that reinforces the initial warming.

Problem 2Difficulty: Mastery

Which question would best help a student evaluate a proposed Earth-system feedback model?

ADoes the diagram use at least four colors?

BDoes the model avoid mentioning variables?

CDoes every label name a continent?

DDoes each arrow show a cause-and-effect loop that amplifies or dampens the starting change?

Solution & Explanation:Evaluating a feedback model means checking causal links and whether the loop returns to the starting condition.

Problem 3Difficulty: Mastery

Use the signed albedo loop diagram for this item. The arrows show: temperature increase causes snow cover decrease; snow cover decrease causes reflectivity decrease; reflectivity decrease causes absorbed sunlight increase; absorbed sunlight increase causes temperature increase. What is the overall loop?

ANo feedback, because reflectivity is not a system variable

BPositive feedback, because the loop ends by increasing the original temperature change

CNegative feedback, because snow cover decreases

DNegative feedback, because one arrow uses the word decrease

Solution & Explanation:The overall loop reinforces the original temperature increase even though some individual variables decrease.
