The AP Environmental Science Exam assesses student understanding of the science practices and learning objectives outlined in the course framework. The exam is 2 hours and 40 minutes long and includes 80 multiple-choice questions and 3 free-response questions.

Photochemical smog is a mixture of pollutants that are formed when nitrogen oxides and volatile organic compounds (VOCs) react to sunlight, creating a brown haze above cities. It tends to occur more often in summer, because that is when we have the most sunlight.

Reducing Pollution

One option is to use coal that contains less sulfur. Another option is to “wash” the coal to remove some of the sulfur. The power plant can also install equipment called scrubbers, which remove the sulfur dioxide from gases leaving the smokestack.

The main source of indoor radon is radon gas infiltration from soil into buildings. Rock and soil produce radon gas. Building materials, the water supply, and natural gas can all be sources of radon in the home. Basem*nts allow more opportunity for soil gas entry than slab-on-grade foundations.

Roughly 9% of all test takers in 2022 received an “extremely well qualified” score of 5. The largest share of test takers—27.4%—received a 4. And 17.5% received a 3.

Look for a small loophole within the two answers and whichever answer seems more suspicious is what you should discard. Logically deduce whether the answer choice you picked fits in the given circ*mstances of the problem. Trust your instincts; if you really feel that one answer is correct, go with it.

Ozone can worsen asthma symptoms, and may contribute to the development of asthma. Elevated exposures to ozone can cause permanent lung damage, and repeated exposure can even increase the risk of dying among persons already in poor health.

Heat waves often lead to poor air quality. The extreme heat and stagnant air during a heat wave increase the amount of ozone pollution and particulate pollution.

Growing up breathing high levels of air pollution can affect how children's lungs develop, putting them at greater risk of lung disease as they age. Older adults are at increased risk of harm from air pollution for several reasons.

An SO₂ scrubber system is the informal name for flue gas desulfurization (FGD) technology, which removes, or "scrubs," SO₂ emissions from the exhaust of coal-fired power plants.

What are 10 advantages of coal? ›

All oxides of sulfur are highly hygroscopic. Simply increasing the humidity may be enough to react with airborne SO2 and then it will react or stick to the first surface it touches A wet scrubber with a blower will act even faster. A spray bottle of concentrated ammonia would work if you can stand the smell.

Formaldehyde is a common indoor air pollutant. It is a gas that can irritate a person's eyes, nose, throat, and lungs, or trigger an asthma attack, even at low concentrations. Prolonged exposure to formaldehyde can cause cancer.

Common natural pollutants include radon, mold, and dust. Common human-made pollutants include Volatile Organic Compounds (VOCs) and formaldehyde. Common combustion pollutants include carbon monoxide, nitrogen oxides, sulfur dioxide, particulates, and tobacco smoke.

While air purifiers aren't effective against radon, they can improve the air quality in your home in many ways. The right air purifier can cleanse the air you breathe of particles like pollen and dust, harmful chemicals and microorganisms, improving your health and quality of life.

You'll need to demonstrate complex thinking on the AP exam in order to earn a 5, so dig deeper than the surface-level content. Learn how to explain concepts and processes, analyze presented sources and data, and justify proposed solutions. Don't wait until the last minute to focus on this step!

Receiving a 3, 4, or 5 is commonly accepted as scoring well on an AP® exam. According to the College Board a 3 is 'qualified,' a 4 'well qualified,' and a 5 'extremely well qualified. ' Depending on the school you plan to attend, college credits can be available for scores within the 3-5 range.

Usually, a 70 to 75 percent out of 100 translates to a 5.
