Question

Explain circumstances leading to acid rain. How does acid rain affect us?​

Answer 1

Answer:

Explanation:

Acidic rain is a rain or any other form of precipitation that

is usually acidic, meaning it possesses elevated level of hydrogen ions. Acid

rains are caused due to emission of sulphur dioxide nitrogen dioxide and chlorofluorocarbon

which reacts with water molecules in atmosphere producing acid rain. NOx, SO2,

CFCs are released due to increasing industrialisation, smoke emitted from

vehicles, gases released from smokestack to reduce local pollution into

regional atmospheric cycles. Natural factors such as volcanic eruption cause

into emission of SO2 and lightning strikes may cause NO2.

Adverse effects on biotic and abiotic things:

1. Aquatic Animals and Oceans:

Lowering of pH & higher aluminium concentration

in surface water due to acid rain can cause damage to fish & other aquatic

animals. Coral’s limestone skeleton are sensitive to pH drop.

2. Soil and forest:

Soil biology and chemistry can be seriously

damaged by acid rain, this can also affect forests & other vegetation.

3. Human Health:

Acid rains don’t directly harm to

human health, but it may cause into serious harms due to dry deposition in air which

can contribute to heart & lung problems including asthma & bronchitis.

4. Infrastructure & Marble Eroding:

Infrastructure can get eroded due to acid

rain. It also corrodes marble which is known as “Marble cancer”. Industries

located in Agra are responsible for higher production of pollutants causing for

yellowing of marble of Taj Mahal.

Hope it helps

Answer 2

Answer:

Sulphur dioxide and nitrogen dioxide are the type of pollutants, which are released into the atmosphere by the burning of fossil fuels like diesel and coal. These pollutants react with the water vapours present in the atmosphere to form nitric acid and sulphuric acid respectively. By precipitation, these acids come down and form the acid rain.

Effects caused by the acid rain:

a) It destroys the crops.

b) Harmful for the building especially to those made of white marble like the Taj Mahal.
