Chapter 15/19 Study Guide- APES, GVHS
Photochemical smog, aka
Brown Smog, LA-Type smog
U.S. Clean Air Act of 1970
Defined 6 pollutants that threaten humans, ecosystems, and structures
Why do developed countries have to reduce CO levels more than developing countries have to?
Developing ccountries are unfarily exposed to the consequences of global warming that in large part come from the developed nations
WWhat is carbon sequestration
Taking CO2 out of the atmosphere
What are volatile organic compounds
Used generally in building furntirure
What does a scrubber do?
Uses a combo of water and air to seperate and remove particulate mater
Pollutants from plants?
VOC's- ethylene
Thermal inversion
When a warm layer of air covers a layer of cold, dense air below
Sulfurous Smog
aka London-type smog, gray smog
What level of the atmosphere are wwe concerned about when we talk about air pollution? Why?
Troposphere, b/cc it occurs not just in one place but everywhere.
What is ground-level pollution?
Tropospheric pollution
What will happen to cold spells as of global warming?
As temperatures increase, there will be fewer days below freezing
Chloroflourcarbons (chemical formula)
CFC's
Which GHG listed has the largest global warming potential?
CFC's
Carbon Dioxide (chemical formulaa)
CO2
Fluidized Bed Combustion
Granulated coal is burned in cclose proximity to ccalcium ccarbonate
Water Vapor (chemical formula)
H2O gas
When is Antarctica's spring?
In August-November
Where is ozone harmful?
In the lower atmosphere (troposphere), bc it acts as a ghg that can cause warming of the earth
How did Chattanooga's geography contribute to its air pollution problem?
It is loccated in a natural basin, the surrounding mountains trao the pollutants above the city
What does an electrostatic precipitator remove
It makes particcles or somthing im tired
Methane (Chemical formula)
NH4
Pollutants from Lightning?
NItrogen Oxides
(feedback loop) as temperatures increase, more water evaporates, forming more clcouds
Negative
WWhat is CCcarbon Monoxodie
Outdoor air pollutant, no odor
What does a baghouse remove
Particculate matter
Pollutants from forest fires?
Particulate matter, nitrogen oxides, Co
What are primary pollutants?
Pollutants directly out of smoke stack
Secondary pollutants ?
Pollutants that went through transformation in sunlight, water, oxygen
What is radon-222
Radioacctive gas that occurs naturally from the decay of uranium
Pollutants from volcanoes?
Sulfur dioxide, particulate matter, CO
Criteria Air Pollutants
Sulfur dioxides, nitrogen oxides, carbon monoxide, particulate matter,
What is Asbestos?
The long, thin, fibrous siliccate mineral with insulating properties
Where is ozone helpful?
The stratosphere, bc it filters out harmful UV rays
How can China be a leading producer of CO2 but have relatively low per capita production?
They're a developing country, w/ many new building ccoal-powered electrical i dont fig knoww
Inversion layer
This time the warm inversion layer traps emissions
