Pollution
the type of pollution emitted directly from the source
what is primary pollution?
energy sources that can be replenished at the rate they are consumed
what is a renewable resource?
released during ore and metal processing and from aircraft that use leaded fuel, in old paints (before 1978) and pipes (before 1986)
what is lead?
adverse effects of excessive artificial light
what is light pollution?
organic substance such as coal, oil, or natural gas that is used as an energy source
what is fossil fuels?
released during burning of fossil fuels, created when nitrogen and oxygen interact
what is nitrogen dioxide?
energy that exists in the nucleus of an atom
what is nuclear energy?
primary pollutant in ozone formation and acid rain
what is nitrogen dioxide?
places where the darkness of the night sky is relatively free of interference from artificial light
what is dark sky?
energy sources that can be replenished at least at a rate equal to that which they are consumed
what are renewable resources?
what are primary pollutants?
coal, oil, nuclear, and natural gas are all considered this type of resource
what are nonrenewable resources?
paints and coatings, formaldehyde is one of the most common found in building materials such as plywood, particleboard, and glues
what are VOCs?
what is the greenhouse effect?

focus the sun's energy that falls over a large area on a small location, it can be used to generate electrical energy even during the night if thermal storage systems are used
an energy dense fossil fuel with infrastructure in place, multiple types of fuel can be created with refined raw material
what is oil?
