Which of the following
gases help form the
earth's protective shield?
- Stratospheric Ozone
In a refrigerant system,
the device that changes a
low pressure vapor to a
high pressure vapor is
the: - compressor.
Data shows that chlorine
in the stratosphere comes
mainly from CFCs rather
than from natural sources
such as volcanoes
because: - The rise in the
amount of chlorine in the
stratosphere matches the
rise in the amount of
fluorine, which has
different natural sources
than chlorine; The rise in
the amount of chlorine in
the stratosphere matches
the rise in CFC emissions;
Air samples taken from
the stratosphere over
erupting volcanoes show
that volcanoes contribute
a small quantity of
chlorine to the
stratosphere when
compared to CFCs;
Which atom of the CFC
molecule causes ozone
depletion? - chlorine
The ozone layer protects
the earth from: -
ultraviolet radiation from
the sun.
