WorksheetsIB Y13 Unit 6.3 Photochemical Smog
Total questions: 15
Worksheet time: 8mins
What effect do temperature inversions have?
traps heat and raises the temperature beneath it
traps cold air and lowers the temperature beneath it
traps emissions and can accumulate beneath it
traps the ozone layer
What is the source of nitrogen oxides?
Animal and plant processes
Volcanic eruptions and fires
Solvents, glues and paint
Incomplete combustion of gas or diesel fuels in vehicles.
Which of the following is not an example of a volatile organic compound? (VOC)
carbon monoxide
paint thinner
gasoline
air freshener
SECONDARY pollutants can result from the reaction of VOC's and nitrogen oxides with ____
warm temperatures
cold temperatures
CO2
sunlight
Both geography and weather contribute to the formation of smog.
True
False
How do temperature Inversions affect air currents?
A layer of cold, polluted air mixes with the warm air from the surface and creates a smog-like layer
A layer of slightly warmer air prevents the warm, polluted air from rising, causing a build up of pollution near the surface
A layer of smoke causes temperatures to lower near the surface of the earth, causing more pollution in the air.
Which compounds are mainly responsible for the formation of photochemical smog?
Carbon monoxide and sulfur dioxide
Nitrogen oxides and volatile organic compounds
Methane and carbon dioxide
Chlorofluorocarbons and water vapor
What is the role of sunlight in the formation of photochemical smog?
It cools down the pollutants, reducing smog formation
It acts as a catalyst in the chemical reactions that produce smog
It has no significant role in smog formation
It dissolves the pollutants in the atmosphere
What are the two types of ozone mentioned in the document?
Atmospheric and Ground-level Ozone
Stratospheric and Mesospheric Ozone
Stratospheric and Tropospheric Ozone
Kitchen and bathroom Ozone
What health effects can be caused by PANS (Peroxyacetyl nitrates)?
Irritates eyes, nose, and throat
Improves respiratory function
Reduces risk of heart disease
burnt scrambled eggs
Which of the following is a method to reduce photochemical smog?
Increase use of fossil fuels
Use EV, ride a bike, or use public transportation
Remove catalytic converters
Increase VOC emissions
Why are thermal inversions dangerous in large cities, high traffic areas, and industrialized regions?
They allow for better dispersion of pollutants.
They cause a decrease in air temperature.
They trap pollution below the warm layer and prevent it from dissipating.
They increase the humidity levels in the air.
Which of the following is NOT a primary pollutant?
Sulfur Dioxide
Nitrogen Dioxide
Volatile Organic Compounds (VOCs)
Sulfuric Acid
The pollution of the air we breathe is an example of
good stewardship
anthropogenic mitigation
tragedy of the commons
over-regulation of the government
Which season has the highest amount of ozone concentration?
winter
spring
summer
fall
