AIR QUALITY PRACTICE 100% SOLVED
Solar power is a renewable resource because _______.
a.
it is continually replenished
b.
using the resource consumes it
c.
it can be found everywhere on earth
d.
all of the above - answer A. It is continually replenished
Explain how burning fossil fuels can lead to a lower ocean pH. - answer Carbon dioxide (CO2) is
one of the principal pollutants released by burning fossil fuels. When carbon dioxide is dissolved
in water it forms acid which lowers the pH. In this way the CO2 produced by burning fossil fuels
can result in lower ocean pH.
Explain why acid rain, smog, ocean acidification, and global warming are indirect results of air
pollution. - answer In all of these cases the impact of air pollution is not directly related to the
toxicity of the gases. Acid rain and ocean acidification occur when pollutant gases react in the
environment to form acid. Smog impacts the environment by filtering out sunlight and leaving
less available for plants to use. Global warming occurs because greenhouse gases cause earth to
retain more of the heat it collects from the sun.
It is best to say that most human sources of air pollution result from _______.
a.
forestry management
b.
fuel burning
c.
