what is harmful effect of acid rain in 200 words..
Answers
Explanation:
Acid Rain includes rain, snow, hail, fog, or dew that is high in acid pollutants, especially sulphuric and nitric acid. Acid Rain is mainly caused by emissions of sulphur dioxide and nitrogen oxide from various sources. They react with the water molecules in the atmosphere to produce acids. The problem of Acid Rain has not only increased with rapid growth in population and industrialization, but it has also become more harmful. In fact, the use of the tall chimneys on a factory, ship, has contributed to the spread of Acid Rain by releasing gases into the atmosphere. A large number of acid deposits are witnessed in Canada, the United States, Europe, portions of Sweden, Norway, and Germany. Some amount of acid deposits are found in parts of South Asia, South Africa, Sri Lanka and Southern parts of India like Bangalore, New Delhi, Mumbai.
Types of Acid Rain
There are two types of depositions in which acid rain occurs. They can be discussed as follows:
Wet deposition: When the acid falls on the ground in the form of rain, snow, fog or mist, it removes acid from the atmosphere and settles them on the Earth’s surface. When this acid flows through the ground, it affects a large number of plants, animals and aquatic life. The water from drain flows into the water sources like rivers and canals which is then mixed up into seawater; thereby affecting the aquatic habitats.
Dry deposition: When the acidic pollutants merge into dust or smoke and fall to the ground as dry particles, these stick to the ground and other surfaces such as buildings, cars, houses, trees, and monuments. Majority of the acidic pollutants in the atmosphere spread through dry deposition.

Causes of Acid Rain
The major causes of acid rain are Natural and Human-Instigated causes. However, Acid Rain is basically caused due to the combustion of fossil fuels which results in emissions of sulphur dioxide (SO2) and nitrogen oxide (NO2) in the atmosphere.
Natural Sources: The main nature causing agents for acid rain are volcanic eruptions. Volcanoes emit a large amount of lava, producing harmful gases which create a higher than normal amount of Acid Rain. Decaying vegetation, wildfires and other biological processes within the environment also generate the Acid Rain forming gases. Lighting strikes also produce nitric oxides that react with water molecules via electrical activity to produce nitric acid, thereby forming acid rain.
Answer:Air pollution like sulfur dioxide and nitrogen oxides can cause respiratory diseases, or can make these diseases worse. ... The pollution that causes acid rain can also create tiny particles. When these particles get into people's lungs, they can cause health problems, or can make existing health problems worse
