Acid rain
Rain that is more acidic than normal
is called acid rain.
In other words the precipitation

• Burning coal, Oil and natural gas, in power stations which use in making of electricity, gives off sulphur dioxide gas.
• Burning petrol and oil in vehicle engines gives off nitrogen oxides as gases.
• When these gases mix with water vapour and rainwater in the atmosphere produce weak solutions of sulphuric and nitric acids – which fall as acid rain.
CAUSES OF ACID RAIN
There are intense
effects of acid rain on
various components:
1. Effects on
monuments and
sculptures..
2. Effects on trees and
vegetation.
3. Effects on aquatic
animals.
4. Effects on humans. 7

stone.
2.These compounds act as bases and

EFFECTS ON AQUATIC ANIMALS
• Acid Rain increases the acidity of lakes
& rivers, which is directly effect the
aquatic ecosystem.
Major respiratory problems.
Asthma, along with dry cough, headache, and throat irritation can be caused by the SO2 and Nox from acid rain.

•Use energy efficient appliances.
•Use public transportation, Whenever
possible walk or use bicycle
•Buy vehicles witTurn off lights, computers,
and other appliances when you're not using
them
•h low NOx emissions, and maintain all
vehicles properly.
•Plant more trees.
PREVENTION
Acid rain is slowly destroying our planet. It is our
responsibility to make sure that we protect the
earth for future generations to enjoy.
We should stop polluting. factories should have use
filters so that less pollution goes in the sky.
We have to educate the children on Environmental
issues.
