|
|
|
what are the causes of nitrogen pollution?
|
acid rain and breathing problems such as asthma.
|
|
|
how is nitrogen pollution involved with pollution in the air?
|
nitrogen pollution is formed from nitrogen in the air when the fuel is burnt.
|
|
|
what are the product when nitrogen reacts with oxygen?
|
nitrogen in the air react with the oxygen in the air to produce small amounts of compounds known as nitrogen oxides(nitrogen monoxide & nitrogen dioxide)
|
|
|
how could we reduce pollution?
|
the most simplest of way to reduce all types of pollution is to use less electricity but if we wanted to reduce amount of pollution from cars we could use catalytic converters or use electric cars.
|
|
|
what are the elements that power stations create when they burn coal?
|
they create sulfur dioxide and and carbon particulates.
|
|
|
a 3 year old car has to pass a test called a MOT why?
|
because there is a legal limit to the amount of pollution your car can use so the test is to see how well your car is running and see what needs replacing to reduce pollution.
