Transcript of Acid Rain

Acid rains are produced when fossil fuels like coal and oil are burned in power stations, factories and in our own homes. Most of these acid gases are blown into the sky, and when they mix with water, it can cause rain - or snow, sleet, fog, mist or hail - to become more acidic.
What are the causes of acid rain
Acid rain is caused by a chemical reaction when 2 or more acids mix together like sulfur dioxide and nitrogen oxide are released in the air. The go very high in the atmosphere and react with water, which form acidic pollutants (acidic pollutants are harmful substances like sulphur oxide and create acid as it mixes with water or oxygen.
Humans are another reason why acid rain is produced, humans create so many new chemicals which get released in the atmosphere making acid rain when mixing with water.
Some rains are naturally acidic with the PH level of 5, but human activites is making it slowly increase into an alkali.

What are the effects of acid rain?
The harm to people and the environment is not direct.Walking in acid rain is not that dangerous but it is sort of.However, the pollutants that cause acid rain which are sulfur dioxide (SO2) and nitrogen oxides (NOx) do damage human health. Many scientific studies have identified a relationship between elevated levels of fine particles and increased illness and premature death from heart and lung disorders, such as asthma and bronchitis.Acid rain can cause buildings, statues and bridges to become worse faster .It also harms thousands of lakes,streams and rivers world wide. It disrupts the ecosystems of the lake and kills wildlife in the affected lake,river or stream.Acid rain also damages soil and the tree roots.

What can we do to reduce acid rain?
Energy consumption can create large amounts of acidic pollutants, to reduce acid rain we should conserve energy by :
Turn of any electronics that are not being used currently, it takes up a lot of energy which gives high chances of acid rain.
Use and buy electronics that consume less energy, these such products may have the energy star label which means this consumes less energy.
Try to limit using air-conditioning and control the thermostat ( that controls the temperature of the air-conditioning) while you are away and not in your house.
Cars and trucks create a lot of nitrogen oxides so try to carpool or go on public transport more often, such as : public buses, public trains etc..
If a place is near by walk or bike to that destination instead of driving and using a car.

Where is acid rain helpful?
Questions and Answers
Acid Rain
What is Acid Rain?
After 20 years of re-search scientist have finally discovered that the nitrogen oxide helps is forest productivity .Some scientist have been monitoring and measuring the temperature, moisture level and amount of nitrogen oxide produced by acid rain, they have found that trees grow faster with higher temperature and keeps more carbon with great amounts of nitrogen which is also produced by acid rain.
It helps slow down the global warming.It can lessen the effects of pollution.It also reduces green house gases and even makes lime stone caves.

2.How has acid rain harmed living and non- living things?
Acid rain can cause health problems like respiratory diseases. Acid rains can be extremely harmful to forests. Acid rain that goes into the ground can dissolve nutrients, such as magnesium and calcium, that trees need to be healthy. Acid rain damages lakes and streams. This increases in acidity levels can be deadly to sea wildlife.

4.How can we prevent acid rain?
We can prevent it by reducing pollution, by produce energy without using fossil fuels like coal. instead, people can use renewable energy sources, such as solar and wind power, cars and trucks are major source of pollutants that cause acid rain.
