Why is it harmful?
Acid Rain Presentation

What is acid rain?
Acid rain is produced when the pure rain pour from the sky and combined with certain chemicals in the air such as Sulfur dioxide and Nitrogen oxide. These chemicals can rise very high into the atmosphere and react with some other chemicals to produce more acidic pollutants known as acid rain. Sulfur dioxide and Nitrogen oxide are very easy to dissolve in water and spread out through the atmosphere. As a result of this we experiences sleet, snow, fog and rain these days. It also reduces the level of PH and turned it into acidic water. The Ph of normal rain is 5.6, if it is less than 5.6 we can assume that the rain is acidic.
Power Station
How can we prevent?
We can help to reduce the formation acid rain by cutting the amount of pollution released from the power plants.
The causes of acid rain:
Power Stations- Releases majority
of Sulfur dioxide by burning coals to
generate electricity
Vehicles - Releases Nitrogen oxide by
burning petrol and oil in Vehicle engines.
It is harmful because the
substances in the air such as
Sulfur dioxide and Nitrogen
oxide harms...
Respiratory system
Lakes & Streams

Building & Statues
Respiratory system

it makes our respiratory system hard to breath and it worsen the existing health problems.
especially people who have asthma suffer more because the tiny particles that comes from acid get into people's lungs.
when acid rain seep into the ground it absorbs the nutrients such as Magnesium and Calcium which are the require nutrients for trees to be healthy. Acid rain also causes Aluminum to be released into the soil which make it difficult for trees to take up water. As the results of this the whole tree may die, the leaves may become necrosisand the tissues may damage.
Lakes & Streams
Most of the aquatic lives are
killed by acid rain. The flow of water
contains poisonous metal ions that
kills fishes and water plants.
Building & Statues
Acid rain effect building and statues
by peeling off its paints and make it
appear old and worn out, which reduces
the beauty of it.
By limiting the amount of energy which we consume everyday:
Turning off the light when we're not using it.
Turning off the power in an electrical equipments when they are not in use.
And also
Using renewable energy resources. Example,
Solar energy and wind power.
