EOH353 CH10 Air Pollution Midterm 2 Part 1
What is the current major cause of air pollution in California?
True or false. The air in 2011 is much dirtier now than it was in 1980.
The atmosphere was initially generated by a process called what?
What is the process of
When rocks are heated up, they release gases.
What are the 4 main atmospheric gases?
In radiation, what does Lambda represent?
What are the broad categories of the Electromagnetic Spectrum?
Radiowaves / TV Waves
What are the three types of UV radiation?
What is the relationship between Wavelength and Energy?
What does it mean when energy waves go through
Energy waves that are reduced, then bounced around in the atmosphere.
What keeps our global temperature cool?
What keeps the earth's surface warm at night?
of Infrared light
Most of the Greenhouse Effect is due to water in the atmosphere?
What is the biggest contributor to the Greenhouse Effect?
What do you get when you add O2 + O. (radical)?
O3 - Ozone
True or false. Ozone is very stable.
False. Ozone is very unstable.
In what layor of the atmosphere is natural occurring Ozone located?
In which layer of the atmosphere does Ozone become a pollutant?
Which layer of the atmosphere do we live in?
Which UV radiation breaks apart O3 to O2 and O radical?
Chloroflourocarbons (CFCs) were invented as what?
When were CFCs used widely?
1960s to 1970s
How often does Chlorine destroy 100,000 Ozone molecules?
True or false. Bromoflourocarbons work just as well as CFCs.
Why weren't BFCs used instead of CFCs?
Because BFCs are much more expensive
What was the problem with Bromine in relation to Ozone?
It is much more efficient and it would have even more quickly eaten away at the Ozone layer.
Where is the hole in the Ozone layer located?
What two countries does the hole in the Ozone layer adversely affect?
Over 90% of nonmelanoma skin cancers are due to what kind of UV exposure?
Which city has the worst air quality of any city in the United States?
What type of system sits over the LA Basin most of the year and pushes the air down?
High Pressure System
The High Pressure System diverts cold, rainy weather where?
What is the negative aspect of High Pressure System?
It keeps anything that we throw up into the air... like pollution
What is the
Environmental Lapse Rate
The air turns - 3.5 deg F every 1000 feet
What happens to the Environmental Lapse Rate in a High Pressure System?
Instead of air getting cooler as it rises, the air gets warmer
What is the
Inverted meaning that instead of getting colder, air gets warmer due to increasing pressure.
Pressure = 1/Temp
What we view as the smog line is actually what?
The Inversion Layer
True or false. There is a natural haze in the LA Basin due to the High Pressure System.
What can break up the High Pressure System temporarily?
Strong wind like a storm
