Define: Pollution

Define: Acid Precipitation

           o   Acid Precipitation occurs when anthropogenic (human made) chemicals are released into the
               atmosphere and create an acid

Define: Neutralize

           o   effects of acid precipitation are:

                       1:

                       2:

                       3:

                       4:

At one time, ‘the solution to pollution was dilution’ was the answer to pollution. In your own words, what
does this statement really mean?

   -   oil spills
           o effects
                   kills sea birds because they ingest it and the presence of the oil makes the birds
                     unable to insulate themselves against the cold

           o   cleaning up oil spills
                                                   involves vacuuming the spilled oil off the top of the water

                                                   involves introducing micro-organisms that feed on oil into
                        the water body

                                                   involves lighting the oil spill on fire and letting it burn away
                        (causes air pollution rather than water pollution)

                                                such as detergents break oil up into smaller droplets that
                        can be spread farther and are therefore less concentrated

       Why is water our most precious renewable resource? (give at least 3 reasons)
