8.1 Ozone Flashcards
ozone formula
O3
where is the ozone layer loctaed
in the stratosphere (second layer of atmosphere)
what does the ozone layer do
protects us from super strong UV rays
how Is ozone formed
oxygen reacts with UV
what is a substance that is bad for ozone layer
CFCs
CFCs
chlorflourocarbons
why are CFCs bad for ozone layer
bc they can break it down
where is ozone bad and where is it good
bad on surface good in its layer
why is ozone bad on the surface
bc its highly reactive and can cause damage to tissues like respiratory tissues
how is ozone formed on earth
UV + VOCs + NOx
stratospheric ozone depletion
when man made objects (like air spray which releases CFCs) release things that break down the oxzone in the ozone layer
ozone depleting substances
substances that break down ATMOSPHERIC ozone
examples of ozone depleting substances
CFCs
hydrobromofluorocarbons
Nitrous oxide
why is a skinnier ozone layer bad
allows for more UV radiation to rech earth
why is a lot of UV radiation bad
can cause cancer cataracts lower plant productivity and more
are there holes in the ozone layer or is it getting skinny
getting skinnier
Montreal Protoool
global treaty that aims to phase out all ozone depleting substances
US clean air act amendments
allow the EPA to regulate ozone depleting substances with strict penalties for noncompliance
potential solutsions to limiting the use of ozone depleting ubstances
replacing them with Hydrochlorofluorocarbons, perflourocarbons
limitation to replacing ozone depleting substances with hydrochloroflourocarbons
chlorine still depletes the ozone layer
limitation to replacing ozone depleting substances with perflourocarbons
is a greenhouse gas
clean air act
allow the EPA to being regulating ozone depleting substances
effect of melting ice crystals in the atmosphere
catalyzes the chemical reaction to break down ozone
halon
substance that is an ozone depleting substance
