Acid Rain refers to a highly acidic rainfall, which causes material atmospheric and environmental depletion. It majorly affects the plants, aquatic creatures, infrastructure etc. Being acidic means it contains elevated level of hydrogen ions, i.e., low pH. In fact, normal rain water is already slightly acidic with a pH range of 5.3-6.0, because carbon dioxide and water present in the air react together to form carbonic acid, which is a weak acid. When the pH level of rain water falls below this range, it becomes Acid Rain.
effects of acid rain on crops........
Acid rain affects plants directly and decreases soil quality to reduce yields from agriculture. Its effects are particularly severe in locations near sources of sulfur dioxide and nitrogen oxides.
effects of acid rain on soil............
Scientists believe that acidic water dissolves the nutrients and helpful minerals in the soil and then washes them away before the trees and other plants can use them to grow. At the same time, the acid rain causes the release of toxic substances such as aluminum into the soil.
effects of acid rain on iron bridges...........
since we know that acid rain contains harmful chemicals Well,Just a bit of acid rain can negatively affect the worth of metal items just like iron bridges corrosion can sharply reduce the value these bridges
effects of acid rain on limestone and marble.........
Acids have a corrosive effect on limestone or marble buildings or sculptures. It is well established that either wet or dry deposition of sulfur dioxide significantly increases the rate of corrosion on limestone, sandstone, and marble.
therefore acid rain is never a advantage
hope it helps....
Acid rain is caused by pollution by the gases like Oxides of Sulfur and Nitrogen. It can led to crop failure, it can make the soil acidic. Due to this many iron bridges become weak. It can cause marble cancer to marble monuments like Taj Mahal in India.
