ESS- Atmospheric System and Societies

name of solar radiation absorbed by protective layer of ozone found in the stratosphere

Ultraviolet Radiation

Gases with the largest percentages in the troposhere

Nitrogen, Oxygen

List Ozone depleting sources

Aerosol Sprays, Halogenated Pesticides, Refrigerants, Flame retardants

Name of two gases produced with Nox and Sox dissolve in water

Sulfiric and Nitric acids.

effects of increased uv radiation

damage to photosynthetic organisms

primary pollutants from combustion of fossil fuels

CO, CO2

what does smog depend on

topography, climate, population density, and fossil fuel use

thermal invasions

lack of air movement when cool air is trapped beneath warm air causing pollutants to build up near the ground

pollution management strategies for smog

consume less fossil fuels, use of catalytic converters, government fuel regulations

primary pollutants of acid deposition

SO2, NOx

effects of acid deposition

acid on aquatic organisms, leaching of plant nutrients, increased solubility of metal on fish

pollution management strategies for acid deposition

consume less fossil fuels, use scrubbers, international and national agreements

clean up measures for acid deposition

spreading limestone on acidified lakes or damaged systems

the impacts of acid deposition may be limited to…

areas downwind of major industrial regions

height of troposphere

0-10km

stratosphere

10-50km

clouds in the troposhere…

play an important role in the albedo effect (light reflected from earth)

what does the greenhouse affect do?

maintains suitable temperatures for living systems

Montreal Protocol

international agreement for the reduction of the use of ozone-depleting substances signed under UNEP direction

what does acid deposition do to soil?

removes minerals and nutrients
