This type of power plant emits SO₂ and NOₓ that lead to acid rain formation.
coal-fired power plant
identify 2 key pollutants that react with sunlight to form smog
NOₓ and VOCs
Atmospheric phenomenon shown when warm air sits above cooler surface air.
thermal inversion
Law that banned lead in gasoline in the U.S.
Clean Air Act
identify 2 ways Los Angeles residents could reduce ozone days
using public transportation / biking /walking/carpooling
This type of bedrock can neutralize acid rain due to calcium carbonate.
limestone
This type of light is required for photochemical smog formation.
UV light (sunlight)
A thermal inversion traps pollutants near this location.
Earth’s surface
Major pollutant removed by electrostatic precipitators.
particulates
Best way to improve validity in an experiment
increasing sample size, increasing trials
Describe 2 soil ions that indicate acid rain damage near coal plants
decreased calcium and increased aluminum
Technology in cars that reduces NOₓ and hydrocarbons.
catalytic converter
City in the U.S. that regularly experiences inversion-enhanced smog
Los Angeles
Three main anthropogenic sources of gaseous pollutants in the U.S.
industry, transportation, and energy production
Primary source of radon in homes
uranium breakdown in soil/bedrock entering through foundation cracks
Short-term remediation method for an acidic pond
(pH dropped from 8.2 to 5.2)
adding calcium carbonate
Reducing hydrocarbons would cause this pollutant to decrease.
ozone (O₃)
Major health effect associated with inversions.
increased respiratory irritation
Major environmental disadvantage of storing coal ash.
toxic metal leaching (arsenic, mercury, lead)
An experiment sample went from 30% energy output to 150% energy output. How much more effective was the second sample?
5 times more effective
Explain how acid rain forms (chemical rxn)
SO₂ and NOₓ react with water vapor to form sulfuric and nitric acid
Explain why Los Angeles experiences severe smog.
frequent thermal inversions + high sunlight + heavy traffic
Explain how inversions increase pollution levels
warm air traps cold air under, the cold air is now at the earth's surface. Warm air usually rises, taking pollutants up and away. Since it is cold air at the surface now, the air does not rise and the pollutants do not go up and away
Natural process that releases CO₂ into the atmosphere.
volcanic eruptions
a major effect of SO2 is ...
acid deposition/rain
