• Other gases i.e. trace gases (like argon, carbon dioxide, neon, helium, and methane)

Identify which gas makes up 21% of the atmosphere.

• Nitrogen

• Oxygen

• Other gases i.e. trace gases (like argon, carbon dioxide, neon, helium, and methane)

Which gas is colorless with rotten egg smell, and the biggest source of power plant pollution, causing respiratory tract irritation and forms sulfuric acid when it reacts with water in the atmosphere?

• Carbon monoxide

• Sulfur dioxide

• Nitrogen oxide

• Ground level ozone

What is the term for pollutants that are formed when primary pollutants react with gases in the atmosphere?

• Primary pollutants

• Secondary pollutants

• Tertiary pollutants

• Particulate matter

Which gas is colorless with a sharp sweet smell, mainly released by vehicles, forms nitric acid when mixed with rain water, and forms photochemical smog when mixed with VOCs?

• sulfur dioxide (SO2)

• carbon dioxide (CO2)

• nitrogen oxides (NOx)

• ground level ozone (O3)

What is the role of the ozone layer in protecting the Earth's surface?

• It absorbs greenhouse gases.

• It absorbs UV rays, preventing overheating and sun damage.

• It produces oxygen for the planet.

• It traps heat to maintain the Earth's temperature.

What environmental issue is caused by the mixing of SO2 and NOx with water, forming sulfuric and nitric acids in the atmosphere?

• Global warming

• Ozone depletion

• Acid rain

• Smog formation

What is the purpose of the international agreement called the Montreal Protocol?

• To promote the use of renewable energy sources

• To ban the release of CO2

• To discontinue the use of chlorine-based aerosols and refrigerants (CFCs)

• To eliminate the release of SO2 and NOx

What is the purpose of a catalytic converter for reducing vehicle emissions?

• Using electric vehicles to eliminate emissions

• Passing engine exhaust through a series of precious metals that chemically change the gases into less harmful forms
