Best answer: Which of the following are natural causes of acid rain?

The precursors, or chemical forerunners, of acid rain formation result from both natural sources, such as volcanoes and decaying vegetation, and man-made sources, primarily emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) resulting from fossil fuel combustion.

What are natural causes of acid rain?

Natural Sources

The major natural causal agent for acid rain is volcanic emissions. Volcanoes emit acid-producing gases to create higher than normal amounts of acid rain or any other form of precipitation such as fog and snow to an extent of affecting vegetation cover and health of residents within the surrounding.

What are 3 causes of acid rain?

Power plants release the majority of sulfur dioxide and much of the nitrogen oxides when they burn fossil fuels, such as coal, to produce electricity. In addition, the exhaust from cars, trucks, and buses releases nitrogen oxides and sulfur dioxide into the air. These pollutants cause acid rain.

Which of the following are natural resources that acid rain effects?

Acid rain and fog also damage forests, especially those at higher elevations. The acid deposits rob the soil of essential nutrients such as calcium and cause aluminum to be released in the soil, which makes it hard for trees to take up water. Trees’ leaves and needles are also harmed by acids.

Which common acid is found naturally in rain?

Wet deposition is what we most commonly think of as acid rain. The sulfuric and nitric acids formed in the atmosphere fall to the ground mixed with rain, snow, fog, or hail.

What are examples of natural pollution?

Naturally occurring pollutants include ash, soot, sulfur dioxide, ground-level ozone (also known as smog), salt spray, volcanic and combustion gases, and radon. These pollutants are released during volcanic eruptions, forest fires, and grass fires.

Which of the following pollutant causes acid rain Mcq?

It mostly occurs due to the presence of oxides of sulphur and nitrogen in the atmosphere. Nitrogen and sulphur oxides react with water vapour to form acids. Large amounts of sulphur and nitrogen oxides are emitted from power plants and large industries.

What is the main cause of acid rain Brainly?

Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

What is the natural pH of rain?

Normal, clean rain has a pH value of between 5.0 and 5.5, which is slightly acidic. However, when rain combines with sulfur dioxide or nitrogen oxides—produced from power plants and automobiles—the rain becomes much more acidic. Typical acid rain has a pH value of 4.0.

What is acid rain class 10th?

Acid rain is rain that is unusually acidic and highly corrosive in nature. … It may be defined as “rain water having pH less than 5.6”. Acid rain can have harmful effects on plants, animals and humans. It is caused when gaseous compounds of ammonium, carbon, nitrogen, and sulphur are released into the atmosphere.

What is acid rain Its Causes effects and solutions?

Sulfur dioxide (SO2) and nitrogen oxides (NOx) released into the air by fossil-fuel power plants, vehicles and oil refineries are the biggest cause of acid rain today, according to the EPA. Two thirds of sulfur dioxide and one fourth of nitrogen oxide found in the atmosphere come from electric power generators.

What are two effects of acid rain?

Acid rain leaches aluminum from the soil. That aluminum may be harmful to plants as well as animals. Acid rain also removes minerals and nutrients from the soil that trees need to grow.

Which of the following would not cause acid rain?

Carbon dioxide reacts with water to form carbonic acid thus contributing to acid rain. So, from all these gases only carbon monoxide does not react with water to form an acid. Thus, not contributing to the acid rain, So, the correct answer is “Option C”.

IT\'S FUNNING:  What are the two main factors that determine the rate of weathering?

Does no2 cause acid rain?

NO2 and other NOx interact with water, oxygen and other chemicals in the atmosphere to form acid rain. Acid rain harms sensitive ecosystems such as lakes and forests.

Why is unpolluted rainwater naturally acidic?

Carbon dioxide, produced in the decomposition of organic material, is the primary source of acidity in unpolluted rainwater.
