Acid Rain Process

| |


      Harmful Chemical Produced
                Factories, cars, and trucks release smoke containing chemicals into the air. These chemicals are acids, substances that can destroy the objects they touch. Some of these acids fall on land, lakes, rivers, and streams.
     Acids Mix with Clouds
                Some acids mix with water vapor in clouds to form acid droplets. Winds can carry clouds with acid droplets for long distances.
    Clouds Drop Moisture
                Clouds release their moisture in the form of acid rain or acid snow. Chemicals in the rain and snow fall on lakes, forests, and buildings.
     Acid Rain Damage
                Chemicals in acid rain and acid snow harm living things. These chemicals can kill entire forests. They poison lakes, streams, and rivers, killing fish and other animals that drink from or swim in these waters. Chemicals in acid rain and acid snow even eat away at the stone of buildings.

                Green House Effect

Greenhouse effect happen because the increasing of carbon dioxide (C02) result of combustion process of fossil fuel (petroleum and embers stone) by industry, transportation, and earns also is caused by forest fire that is often happened. The Increasing Of CO2 on the air gathering in atmosphere layer earth forms a kind ”shield”. This thing causes temperature which exit from atmosphere layer, will be bounced again to earth.
Layer functioning CO2 as reflector to temperature from earth. Hot from earth bounced again to this earth will boost up earth temperature, as a result earth more and more temperature (global of warming). Layer influence CO2 to increase of this earth temperature called greenhouse effect.
