Below are sample questions representative of the exercises included on this worksheet and related 9.26 Human–Environment Interaction and Sustainability skill assessments:

Problem 1Difficulty: Mastery

Pine Ridge is at the edge of a mangrove-lined lagoon. Drinking water comes from a karst aquifer. After a fuel spill, contaminants appeared in springs within days.

Why is contamination spread often rapid in karst systems?

AKarst aquifers are made of solid metal pipes

BKarst eliminates groundwater movement entirely

CKarst turns contaminants into harmless minerals instantly

DWater moves through connected fractures and caves with little natural filtration

Solution & Explanation:Karst terrain has large pathways (caves/fractures) so pollutants can travel quickly and bypass the slow filtering that occurs in fine sediments.

Problem 2Difficulty: Mastery

Cobalt Garden is along a glacier-fed river that peaks in late spring. Two flood plans are compared. Plan A cuts peak flood depth by 20 cm but damages wetlands. Plan B cuts peak depth by 12 cm and restores wetlands.

If the city defines resilience as reducing losses over decades (not just the next flood), which choice is better supported?

APlan A, because any wetland damage has no effect on future floods

BPlan A, because smaller depth reduction is always worse regardless of co-benefits

CPlan B, because restored wetlands provide ongoing flood storage and ecosystem services that reduce long-term risk

DEither plan, because resilience does not include ecosystems or maintenance

Solution & Explanation:Long-term resilience includes natural buffers and maintenance costs; nature-based solutions can provide repeated protection and co-benefits over time.

Problem 3Difficulty: Mastery

Sage Palms is on reclaimed wetlands protected by levees. A plan to expand irrigated biofuel crops would raise summer water withdrawals by 40% and reduce river flow during the hottest months.

Which assessment best captures the sustainability concern?

ABiofuel crops always use less water than native grasslands

BBiofuel energy gains may come at the cost of water security and ecosystem health during peak demand

CLower river flow guarantees more fish habitat and cooler water

DMore irrigation automatically recharges rivers without trade-offs

Solution & Explanation:The food-water-energy nexus highlights trade-offs: more energy crops can reduce water availability and stress ecosystems when flows are already low.
