What are the main causes of acid rain the main causes of acid rain are the emission of and?
and (4) may cause harmful effects on soil, forests, streams, and lakes. Acid rain results when sulfur dioxide (SO2) and nitrogen oxides (NOX) are emitted into the atmosphere and transported by wind and air currents. The SO2 and NOX react with water, oxygen and other chemicals to form sulfuric and nitric acids.
What are three natural causes of acid rain?
Natural Causes of Acid Rain
- Atmospheric Composition. The pH of rainwater in unpolluted regions is 5.6, making it a weakly acidic solution. …
- Volcanic Eruptions. …
- Lightning Strikes. …
- Emissions from Vegetation.
What 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 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 acid rain for class 9th?
Acid Rain is when gases in the atmosphere combines with falling water to form acids, which fall as rain. Two gases which cause it are: Sulphur Dioxide. Nitrogen Dioxide.
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.
Which of the following is a major contributor to acid rain?
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.
How does lightning cause acid rain?
Acid Rain -Nitrogen Oxides. Natural Sources – Lighting Bolts: A natural source of nitrogen oxides occurs from a lightning stroke. The very high temperature in the vicinity of a lightning bolt causes the gases oxygen and nitrogen in the air to react to form nitric oxide.
