Below are sample questions representative of the exercises included on this worksheet and related 4.21 Human–Environment Interaction Adapt and Modify skill assessments:

Problem 1Difficulty: Mastery

A desert resort uses three strategies: it builds shade structures and reflective pavements, imports water through a pipeline, and asks guests to wear breathable clothing and drink extra water. Which statement correctly classifies these strategies?

AAll three are adaptations because they do not change anything outside the human body

BAll three are modifications because they physically reshape the desert

CShade structures and the pipeline modify the environment or infrastructure, while clothing and hydration are adaptations in personal behavior

DOnly clothing is modification because it changes fabric

Solution & Explanation:Building structures and pipelines changes built features and how resources move, which is modification. Changing what people wear and do to stay safe in heat is adaptation.

Problem 2Difficulty: Mastery

After minor landslides, a hillside community proposes removing trees to 'lighten' the slope. Another group proposes planting deep-rooted vegetation and improving drainage. Which proposal is more likely to reduce landslide risk, and why?

ARemoving trees, because bare soil is always more stable

BRemoving trees, because roots make soil slide like wheels

CEither proposal, because landslides are unaffected by water

DPlanting deep-rooted vegetation and improving drainage, because roots strengthen soil and less water reduces slope failure

Solution & Explanation:Roots help bind soil and can reduce erosion. Better drainage lowers water buildup in the ground, which often triggers slope failure. Removing trees usually makes erosion worse.

Problem 3Difficulty: Mastery

A beach town builds several groynes (rock walls perpendicular to the shore). After construction, sand builds up on the updrift side of each groyne, but beaches down the coast become narrower. Which explanation best describes what happened?

AThe groynes increased longshore drift so more sand reached every beach

BThe groynes stopped waves from moving any sand anywhere

CThe groynes interrupted longshore drift, trapping sand in one place and reducing sand supply to down-coast beaches

DThe groynes created new sand from seawater

Solution & Explanation:Groynes can trap sand moving along the shore. If less sand continues down the coast, beaches farther along may receive less replacement sand and become narrower.
