2. Introduction
Acid rain is formed by pollution in the air. Cars power
stations and factories release waste gasses.
The waste gasses mix with water in the air. So that
the rain is polluted.
The water falls to the ground which harms trees ,
plants and pollutes rivers which makes them unable
for animals to live in their natural habitat.
Fact box:
More than 15,000 lakes in
Sweden have been damaged by
acid rain 4,000 of these lakes no
longer have fish in them
Eco Thought:
In Germany it is
estimated that it may
cost as much as 15,000
million to reduce the
effects of acid rain.
3. The Cause of Acid Rain
Introduction:
Two elements, sulphur and nitrogen which react
with water molecules, are primarily responsible
for the harmful effects of acid rain.
Sulphur is found as a trace element in coal and
oil when they are burned in power plants and
industrial boilers.
The amount of sulphur dioxide released into the
air has been falling since 1970, but the amount
of nitrogen has been increasing because the
number of vehicles on the road is increasing.
4. The Cause of Acid Rain Part II
The sulphur and nitrogen comes from
pollution e.g. vehicles, power stations,
factories and electricity. And that is the
cause of acid rain.
5. Acid Rain Effects
PART 1
Acid rain causes acidification of lakes and streams.
Over the years scientists have discovered the
effects of what this has on forests.
Trees should be healthy and should only have
leaves fall of in autumn but due to acidification
there are large groups of trees that are dying.
Nitrogen oxides and sulphur dioxide are the main
gases in acidic rain.
6. Acid Rain Effects
PART 2
Acid rain effects plants just like it effects trees.
Acid rain effects deterioration on paint and
stone. This effect reduces the social value
statues, cars, bridges and buildings. It will rise
maintenance costs.
