Question

what is the cause of acid rain

Answer 1

Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidicpollutants, known as acid rain.

Answer 2

Acid rain:-

❋ If the precipitation has a pH less than 5.6, it is described as acid rain.

❋ This situation occurs when oxides of Sulphur and nitrogen in the atmosphere combine with water vapour and form sulphuric acid and nitric acid respectively.

❋ These precipitate as rain snow or fog. The main source of these oxides are combustion of fuels in the industries.

Effects Of Acid Rain :-

❋ Acid rain effects all forms of life. It affects egg production in aquatic animals and hence, alters the population ratios.

❋ It can affect vegetation since the soil becomes acidic. It leeches the nutrients in soil. The leaves of affected plants develop brown spots and cracks this allows infection of pathogens.

❋ Acid rain is harmful to human health also it causes skin allergies and respiratory problems.

❋ Acid rain also affects old buildings and monuments it damages metal and stone structures.
