These images of the Santa Cruz River in Arizona were taken in 1942 and 1989. During the period between these years, the growth of vegetation declined substantially in the area. What are the two most likely explanations for this change in vegetation?
- The amount of carbon dioxide in the air slightly increased.
- Herbivores (plant eaters) in the area migrated elsewhere.
- The roots could no longer access depleted groundwater.
- The region received a consistent amount of rainfall.
- The topsoil in the area eroded.

| Melissa lives in a town called Greendale. She discovers that when she lights a match and holds it near her kitchen faucet, the little flame grows into a larger fire. Melissa is surprised because she thought the water would extinguish the flame rather than ignite it further. Her mother tells her that the water might be contaminated with dissolved methane, a primary component in natural gas. Melissa investigates the matter and finds that cases of methane contamination started shortly after a company began fracking for natural gas in the area. Based on this information, which three statements are plausible consequences of fracking in Greendale? - Fracking contributed to methane finding its way into the residential water supply. - Fracking is always safe to use in the proximity of Greendale's water supply. - Pressure from fracking forced methane to mix with Greendale's groundwater. - Fracking in Greendale produces more freshwater than it consumes. - If fracking can contaminate city water, it might also poison nearby rivers. | 1st 3rd 5th |
| Tamara lives in the United States. She has been hospitalized several times due to severe respiratory allergies. Ozone affects her condition the most. She enjoys spending time outdoors but is very careful when she steps outside. In which scenario will it be best for Tamara to do her outdoor activities? A. noon in June B. 1 pm in October C. 5 pm in June D. 1 pm in July | B. 1 pm in October |
| Which location is least likely to experience a volcanic eruption? A. an island hot spot, such as the island of Hawaii B. Hamilton County on the plains of central Texas C. a convergent boundary, as in the Ring of Fire D. a volcanic island arc, such as the Aleutian Arc in Alaska | B. Hamilton County on the plains of central Texas |
| A volcanic eruption can be frightening and destructive, but it can also help humankind. Choose two positive outcomes of a volcanic eruption. - Valuable metals can be found in ore near a volcano's base. - Volcanoes emit greenhouse gases into the atmosphere. - Volcanic ash is rich in minerals and makes for good fertilizer. - Volcanic emissions improve air quality, helping those with respiratory problems. | 1st 3rd |

| The city council is planning to construct a new wastewater treatment plant to regulate the amount of pollution currently seeping into the city’s lakes and streams. They plan to build the new treatment plant on the outskirts of the city by clearing a sizable piece of land in a forested area. How will both of these steps impact the city in the long run? A. Because of the urban heat island effect, less heat will be absorbed and regional temperatures will be slightly higher. B. The wastewater treatment plant will solve the city’s air pollution problems. C. The new plant will guarantee that the city’s drinking water will always be free from harmful pathogens. D. Water pollution will decrease, but the number of rock falls in the area will increase. | A. Because of the urban heat island effect, less heat will be absorbed and regional temperatures will be slightly higher. |
| What effect does eutrophication have on aquatic ecosystems? A. It prevents sunlight from reaching aquatic life below the water’s surface. B. It negatively impacts aquatic vegetation but is beneficial for all aquatic animals. C. It decreases carbon dioxide concentration, which is harmful for aquatic animals. D. It lowers the concentrations of nitrogen and phosphorous available to marine animals. | A. It prevents sunlight from reaching aquatic life below the water’s surface. |

| The ocean absorbs carbon dioxide directly from the atmosphere. How does CO2 absorption affect the ocean? A. The acidity of ocean water increases. B. Coral reefs expand, and coral skeletons harden. C. Ocean water becomes colder and denser. D. Saline (salty) ocean water turns into freshwater. | A. The acidity of ocean water increases. |
| Which phenomena release CO2 into the atmosphere? - forest fires - decomposition of organic matter - reforestation - photosynthesis - volcanic eruptions | 1st 2nd 3rd |
| A small town records a substantial increase in atmospheric CO2 levels over a 10-year span. The change is attributed to a rapid growth in the population. Which measure could the residents take to reduce their CO2 emissions? A. Burn discarded materials instead of sorting them for recycling. B. Replace large, mature trees with smaller bushes. C. Carpool to work, ride the bus, or switch to electric cars. D. Install more generators at the town's coal power plant. | C. Carpool to work, ride the bus, or switch to electric cars. |
