Acid rain is the headline for this Weather Tidbits. Acid rain forms from cloud droplets or raindrops that combine with gaseous pollutants, that make falling rain acidic. The pollutants consist of sulfur dioxide (SO2) and nitrogen oxides (NO), that are emitted from industrial areas or volcanic eruptions. Acid rain is known to pollute water sources, destroy plants and weaken trees, which make them susceptible to insects & droughts. It also changes colors of plants and trees, along with eroding historical statues & structures. Acid snow happens as temperatures fall below freezing, but its accumulations are damaging, as huge amounts of acidic water is released once melted.
