Below are sample questions representative of the exercises included on this worksheet and related 6.27 Carbon Cycle and Human Activities skill assessments:

Problem 1Difficulty: Mastery
Use the city carbon-cycle model to answer the question. Which combination of changes would most likely lower atmospheric carbon dioxide over time?
Amore traffic lanes, fewer trees, and more burning of yard waste
Blarger smokestacks, deeper mining, and more clear-cutting
Cfewer plants, more parking lots, and higher gasoline use
Dless fossil fuel burning, more trees or green spaces, and healthier carbon-rich soils
Solution & Explanation:Reducing combustion lowers carbon emissions, while increasing plant growth and protecting soil carbon can increase carbon storage and uptake.
Problem 2Difficulty: Mastery
Which statement would make the best science poster caption about human activities and the carbon cycle?
AHuman actions can add carbon to the atmosphere, reduce natural carbon storage, or increase storage depending on the choices people make.
BPeople do not affect the carbon cycle because only plants move carbon.
CEvery human activity removes carbon from the atmosphere.
DThe carbon cycle matters only in forests and never in cities.
Solution & Explanation:This caption is accurate and balanced because it explains that different human activities can affect carbon in different ways.
Problem 3Difficulty: Mastery
A town keeps a simple carbon budget for one year: +18 units from vehicles and heating, -7 units taken in by growing plants, and -3 units stored in restored wetland soil. What is the net change in atmospheric carbon from these tracked sources?
A+28 units
B-8 units
C+8 units
D0 units
Solution & Explanation:Add the tracked sources and sinks: +18 - 7 - 3 = +8. That means atmospheric carbon increased by 8 units from the sources that were counted.
