What is the difference between acid rain and normal rain

The water vapour in the clouds can come back to the earth surface in the form of rain. And, this is what we call the water cycle. Overview and Key Difference 2. What is Acid Rain 3. What is Normal Rain 4. Water is a universal solvent. When raining, the rainwater tends to dissolve substances, which are dispersed in the atmosphere.

When there are sulfur dioxide and nitrogen oxide gases in the atmosphere, they can easily dissolve in rainwater and come down as sulfuric acid and nitric acid. Then the pH of the rainwater becomes less than 7, and we say that it is acidic. Over the past few decades, the acidity of rain has increased significantly due to human activities.

Nitrogen oxide also forms from fossil fuel burning and power plants. Other than human activities, there are natural processes where these gases forms. For instance, SO 2 forms from volcanoes, and NO 2 forms from soil bacteria, natural fires, etc.

What does it do to the landscape? Can it burn you like battery acid? Keep reading to find out more Water is everywhere, which is fortunate for all of humanity, as water is essential for life. Even though water is not always available in the needed quantity and quality for all people everywhere, people have learned to get and use water for all of their water needs, from drinking, cleaning, irrigating crops, producing electricity, and for just having fun.

The U. When scientists learned that acid rain could harm fish, fear of damage to our natural environment from acid rain concerned the American public. Research by USGS scientists and other groups began to show that the processes resulting in acid rain are very One of the goals of research on the effects of acidic deposition on carbonate stone surfaces is to define the incremental impact of acidic deposition relative to natural weathering processes on the rate of carbonate stone erosion.

Ground-level ozone O3 , unlike other pollutants mentioned , is not emitted directly into the atmosphere, but is a secondary pollutant produced by reaction between nitrogen dioxide NO2 , hydrocarbons and sunlight. Ozone levels are not as high in urban areas where high levels of NO are emitted from vehicles as in rural areas. Sunlight provides the energy to initiate ozone formation; consequently. In the long run, Earth has warmed and cooled habitually since the period of the dinosaurs.

Climate has kept changing as the planet received more or less sunlight due to elusive shifts in the orbit. This term describes an ongoing increase in the average temperature of the. There is cohesion force between the water and oil molecules that allows the two substances to not mix, water molecules cling closer together, that their hydrogen bond cannot be penetrated by the oil until shaken together.

When a oil spill occurs the oil will float on top of water, making it easier to skim or suck away from the water molecules. Since water is denser than oil, it sinks to the bottom. The acidic particles and gases may deposit to surfaces water bodies, vegetation, buildings quickly or may react during atmospheric transport to form larger particles that can be harmful to human health.

When the accumulated acids are washed off a surface by the next rain, this acidic water flows over and through the ground, and can harm plants and wildlife, such as insects and fish. The amount of acidity in the atmosphere that deposits to earth through dry deposition depends on the amount of rainfall an area receives. For example, in desert areas the ratio of dry to wet deposition is higher than an area that receives several inches of rain each year.

Unlike wet deposition, dry deposition is difficult and expensive to measure. When acid deposition is washed into lakes and streams, it can cause some to turn acidic.

The Long-Term Monitoring LTM Network measures and monitors surface water chemistry at over sites to provide valuable information on aquatic ecosystem health and how water bodies respond to changes in acid-causing emissions and acid deposition.
