Question

List four consequences of acid deposition/rain. ["reduces pH" is not a choice]

Answer 1

Following are the consequences of acid rain.

1) Plants and animals are adversely affected as the soil becomes acidic. Also, the nutrients of the soil are leached. Thus, forests and other vegetation are retarded.

2) River and ocean water becomes acidic. This adversely affects the marine life. The pH of fresh water changes which affects the reproduction and survival of many species of fish.

3) Acid rain inhibits the activity of symbiotic nitrogen fixing bacteria present in the nodules of leguminous family. The fertility of soil is destroyed and reduced.

4) Buildings and monuments (made from marble, limestone, slate and mortar) are damaged as sulphuric acid reacts with limestone (calcium carbonate) .

For example, Taj Mahal in Agra slowly degrades due to acid rain.
