Ozone
If you purchased a Ford 2009 Escape Hybrid 2WD vehicle how much in IRS tax incentives could you quality for?
3000
What is the average pounds of CO2 produced by a family of 2 in the US?
41,500
About how much has the Earth warmed (Fahrenheit) over the last 100 years
6-8 degrees
What are some examples of Primary pollutant
CO, CO2, SO2, NO, NO2
This gas enters the atmosphere through the burning of fossil fuels (oil, natural gas, and coal), solid waste, trees and wood products, and also as a result of other chemical reactions (e.g., manufacture of cement). This gas is also removed from the atmosphere (or sequestered) when it is absorbed by plants as part of the biological cycle.
Carbon Dioxide
primary pollutants
Primary pollutants are substances directly produced by a process, such as ash from a volcanic eruption or the carbon monoxide gas from a motor vehicle exhaust.
What are some examples of secondary pollutants
SO3, HNO3, H2SO4, H2o2 O3, PANs Most NO-3 and SO2-/4 salts
Where does ozone form naturally?
Stratosphere
What is the difference between the Troposhpere and stratophere
1. Its volume of water vapor is abut 1/1,000 as much 2. it's concentration of zone is much higher.
What are the possible impacts of global warming
1. Plants and animals may not be able to react quickly enough to survive and mass extinctions could occur.. 2.Climate change also might bring droughts to other places where we grow crops altering world food supplies. 3.Air pollution may increase as a result of global warming 4. Sea level may rise between several inches and as much as 3 feet during the next century. 5.Global water supplies may change 6.heat stress
major classes of Air pollutants
Cardon oxides, sulfur oxides, nitrogen oxides, volatile ogranic compounds (VOCs), Suspended particulate matter (SPM), Photochemical oxidants, Radioactive substances, Hazardous air pollutants (HAPS)
Greenhouse gases
Gases such as carbon dioxide, methane, nitrous oxide, water vapor, and ozone in the atmosphere which are involved in the greenhouse effect.
ODC
Halogen compounds, CFC's
man made industrial greenhouse gases
Hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride, Halocarbons
What are some of the concerns about a thinning ozone layer?
Immune system suppression,Skin cancer, Premature aging of skin, Cataracts
This gas is emitted during the production and transport of coal, natural gas, and oil. This gas is also result from livestock and other agricultural practices and by the decay of organic waste in municipal solid waste landfills.
Methane
What was the first global agreement , established in 1987, o restrict CFCs use and protect the ozone layer?
Montreal Protocol
This gas is emitted during agricultural (fertilizers) and industrial activities, as well as during combustion of fossil fuels and solid waste.
Nitrogen Dioxide
greenhouse effect
The effect produced as greenhouse gases allow incoming solar radiation to pass through the Earth's atmosphere, but prevent most of the outgoing infrared radiation from the surface and lower atmosphere from escaping into outer space. This process occurs naturally and has kept the Earth's temperature about 60 degrees Fahrenheit warmer than it would otherwise be. Current life on Earth could not be sustained without the natural greenhouse effect.
What type of radiation is normally blocked by ozone and may be of some concern if our ozone layer thins?
UVB
how are we studying these long-term climatic changes
Weather Balloons, Ocean Buoys,Weather Satellites Tree Rings, Weather Stations, Ice Cores, Sediment Analyses
CO
an odorless,colorless very poisonous gas that is a product of incomplete combustion of carbon
In a CFC molecule what is the actual part that destroys ozone?
chlorine
Major human sources of CO
cigarette smoking , buring fossil fuels, mostly from vehicle exhaust,
atmoshere
is a thin gaseous envelope comprised mostly of nitrogen and oxygen with small amounts of other gases such as water vapor and carbon dioxide
secondary pollutants
produced by reactions between primary pollutants and normal atmospheric compounds
Health effect of Co
reacts with Hemoglobin in rd blood cells and reduces the ability of blood to bringoxygen to body cels and tissues, which impairs thinig, slows reflexes, causes headaches, drowsiness, dizniness and nausea. Can trigger heart attacks and angina, causes adnormal deveopment in fetues and young children
stratosphere
the layer of the atmosphere immediately above the troposphere
troposphere
the lowest atmospheric layer
