AP Environmental Science Readiness Test

10 questions, balanced across the exam's topics. Answer each one, then submit for your practice readiness estimate and per-topic breakdown. This is a practice estimate — not a prediction or guarantee of your official exam result.

Question 1

Which of the following is NOT a key concept of Aquatic and Terrestrial Pollution?

ecosystem sanitary landfill source reduction biomagnification

Question 2

Which of the following pairings of a concept with its description is correct?

carbon capture and sequestration — electricity generated by turbines whose blades are turned by moving air, with no emissions during operation solar energy (photovoltaic) — technologies that capture CO₂ from emissions and store it underground to keep it out of the atmosphere wind energy — electricity generated when sunlight strikes semiconductor material in a panel, producing current without moving parts or emissions nonrenewable resource — a resource that exists in a fixed quantity and is consumed faster than it can be regenerated, such as coal or copper

Question 3

Which of the following is NOT a key concept of Biodiversity?

ecosystem services HIPPCO population density keystone species

Question 4

Producers in an ecosystem capture 5,000 kcal of energy. Using the 10% law of ecological efficiency, approximately how much energy is available to the second trophic level (primary consumers)?

5,000 kcal 4,900 kcal 4,500 kcal 500 kcal

Question 5

overfishing deforestation monoculture clearcutting

Question 6

All of the following are key concepts associated with Earth Systems and Resources EXCEPT

sea level rise earthquake erosion water table

Question 7

Which concept is described by the following? "The 1987 international treaty that phased out ozone-depleting substances such as CFCs, a landmark environmental success."

Montreal Protocol greenhouse effect climate change positive feedback loop (climate)

Question 8

All of the following are key concepts associated with Populations EXCEPT

total fertility rate Green Revolution density-independent factors carrying capacity (K)

Question 9

Which of the following pairings of a concept with its description is correct?

secondary pollutant — a pollutant emitted directly into the air from a source, such as carbon monoxide from vehicles photochemical smog — air pollution formed when sunlight reacts with nitrogen oxides and volatile organic compounds, producing ozone and a brownish haze primary pollutant — contamination of indoor air from sources such as radon, mold, tobacco smoke, and cooking fires indoor air pollution — a pollutant formed in the atmosphere by chemical reactions among primary pollutants, such as ground-level ozone

Question 10

The concept "endocrine disruptors" is most closely associated with which part of the course?

Aquatic and Terrestrial Pollution Atmospheric Pollution Energy Resources and Consumption Global Change
