Essay March 28‚ 2014 ACID RAIN ENVIRONMENAL EFFECTS What is acid rain? It’s a rain or any other form of precipitation that is unusually acidic‚ meaning that it possesses elevated levels of hydrogen ions (low pH). It can have harmful effects on plants‚ aquatic animals and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide‚ which react with the water molecules in the atmosphere to produce acids. The most obvious environmental effect of acid rain has been the loss

The Effects of Acid Rain Bio-105 Abstract The effects of acid rain is damaging no matter how you look at the picture. Acid rain effects open areas more than forests due to the trees blocking some of the rain from hitting the ground. Acid rain is monitored by using emissions monitors. This helps figure out how much acid is in rainwater. Acid rain is harmful to fish by killing off entire species. Acid rain is harmful to living creatures‚ but many do not realize how toxic it can be to
