Apes Review Unit 9

Which of the following best identifies the reason that chlorofluorocarbons (CFCs) were banned in 1996 by the Montreal Protocol?

• CFCs increased acid deposition in northern latitudes.

• CFCs increased the rates of cancer in workers in mining operations.

• CFCs led to a spike in the number of respiratory illnesses diagnosed in children.

• CFCs led to the destruction of stratospheric ozone.

Which of the following is part of a positive feedback mechanism associated with global climate change?

• Melting of Arctic sea ice

• Increased growth of CO₂ -absorbing trees and grasses

• Increased acidity of seawater

Which of the following best describes how an anthropogenic activity can increase ocean acidification?

• Emissions from power plants that burn fossil fuels increase atmospheric carbon dioxide, which is absorbed by the ocean.

• A spill from an oil rig in the ocean can have acute toxic effects on fish and other aquatic organisms, which disrupt the aquatic food web.

• Tourist activities in coastal areas increase the concentration of sunscreen in the water, which decreases the photosynthetic rates of aquatic producers and increases the pH of the ocean.

• During and after a major volcanic eruption, large amounts of greenhouse gases, aerosols, and ash are released into the stratosphere, which affects global climate.

Which of the following best exemplifies global collaboration for a sustainable environment? (Getting rid of CFCs)

• The Antarctic Treaty of 1961

• The Clean Air Act of 1972

• CERCLA (Superfund)

• The Montreal Protocol

Which of the following best describes the importance of ozone in the stratosphere to life on Earth?

• Ozone reflects X-rays from the Sun back into space.

• Ozone absorbs most of the ultraviolet radiation from the Sun.

• Ozone helps to moderate surface temperature by absorbing CO2 and CH4.

• Ozone increases mutation rates and accelerates evolution in a variety of species.

Which of the following best describes the mechanism of the greenhouse effect in Earth's atmosphere?

• Infrared radiation from Earth's surface is absorbed by gases in the atmosphere.

• Cosmic radiation from deep space is absorbed by gases in the atmosphere.

• Alpha radiation from the Sun is absorbed by water vapor in the atmosphere.

• Ultraviolet radiation from the Sun is absorbed by ozone gas in the stratosphere.

Layer of Earth's atmosphere the contains "good" O₃

• Troposphere

• Hydrosphere

• Mesosphere

• Asthenosphere

• Stratosphere

As the ocean becomes more acidic, the pH of the water

• increases

• decreases
