Acid rain is harmful forA. agricultureB. aquatic ecosystemC. building made of marble or metalD. All of these

Answer» Correct Answer - D
(a) Acid rain decreases soil fertility due to leaching out of plant nutrients.
(b) Due to acid rain, `pH` value of some lakes and streams decreases (and sometimes falls below 3), at which fishes are adversely affected and some varieties are even killed. Dissolution of toxic metals (`Cd,Pb,Al,etc.`) from bottom sediments affect fish and drinking water.
(c ) Acid rain corrodes buildings made of marble and metals. Marble `(CaCO_3)` is badly affected by `H_(2)SO_(4)` (of acid rain).
`CaCO_(3) + H_(2)SO_(4) rarr CaSO_(4)+H_(2)P+CO_(2)`
Metals (especially `Fe`) is also affected by acid rain and causes rusting.
`Fe+2H^(+) rarr Fe^(2+)+H_(2)`
Taj mahal is made of marble `(CaCO_(3))` and is being affected by acid rain.
