What is acid deposition?
|
Precipitation with a pH of less than 5.5
|
|
|
Explain the effects of acid rain
|
*leach nutrients in the ground
*kill nitrogen-fixing microorganisms that nourish plants *kill fish *release toxic metals |
|
|
What are acid rain controls?
|
*fuel switching
*coal washing *scrubbers *fluidized bed combustion *reduced consumption of electricity |
|
|
Describe the Greenhouse Effect
|
*Sun's rays strike the earth & some are converted to infrared radiation that is transmmitted back into outer space
*Some of the infrared is absorbed by greenhouse gases insulating the Earth *more accumulations of greenhouse gases delays the release of infrared to outer space, leading to global warming. |

|
What are the greenhouse gases?
|
*carbon dioxide
*water vapor *methane *nitrous oxide *CFC's |
|
|
What is the role of CO2 in the Greenhouse Effect?
|
*CO2 plays a vital role in moderating the earth's temperature
*Without CO2, The Earth's temperature would be about 90 degrees F cooler *increasing levels of CO2 will have an impact on global climate conditions |
|
|
Describe the impacts of global warming -
|
greater weather extremes, loss of biodiversity,rising sea levels, human illness
|
|
|
How rising sea levels will impact coastal areas?
|
These areas will be permanently buried
|
|
|
How will greater weather extremes impact us?
|
Flood/drought, crop failure, hurricane, life and property damage.
|
|
|
Why will there be a loss of biodiversity?
|
Animals will not be able to migrate to new areas in time. (Nonagricultural species have a narrow range of tolerance to changing conditions)
