1. ACID RAIN
Topic

2. ACID RAIN
The usage and burning of fuels in
factories, vehicles and power plants,
etc., give out harmful gases rise up
,combine with water vapour present in
the atmosphere and form harmful
acids. These acid fall in the form of acid
rain.
Acid rain damages plants , animals and
even buildings. The acidic rain water
also flows into various water bodies
and become a part of water cycle. It
also seeps through the soil thus
affecting the growth of plants.

3. ACID RAIN SIDE EFFECT
• Acid rain is extremely harmful to agriculture , plants and animals
• The PH value of normal rain water is around 5.7, giving it an acidic
nature
• Acid rain also causes the corrosion of water pipes
• The acidic deposition takes place in two different ways :wet and dry
deposition
• Acid rain is a by product of human activity .

4. WHAT ARE THREE WAYS TO REDUCE ACID RAIN?
• Alternative energy sources should be used, such as solar and wind power. Renewable
sources of energy are helping to reduce acid rain, as they produce much fewer
emissions. There are other electricity sources as well, such as nuclear power,
hydropower, and geothermal energy. Among these, the most extensive use is among
nuclear and hydropower.

5. WHAT WILL HAPPEN IF WE DON’T STOP ACID
RAIN?
• Sulphur dioxide and nitrogen oxide are the principal chemicals for acid rain. It can also
influence humans since the acid goes into fruits, vegetables and animals. In other
words, we can get really sick if acid rain doesn’t stop, and we eat those things. In
general, the acid rain affects men, but not directly.

6. DID YOU KNOW ?
The Taj Mahal in Agra is also a victim of
acid rain. Its white marble is slowly
become yellow in colour
•Statue of Liberty which is made of copper has also
been damaged by the cumulative action of acid rain and
oxidation for over 30 years and is, therefore, becoming
green.
