Question

Write any 4 causes of acid rain.

Answer 1

Answer:

• Human activities leading to chemical gas emissions such as sulfur and nitrogen are the primary contributors to acid rain. The activities include air pollution sources emitting sulfur and nitrogen gases like factories, power generations facilities, and automobiles.
• 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.
• The harm to people from acid rain is not direct. Walking in acid rain, or even swimming in an acid lake, is no more dangerous than walking or swimming in clean water. However, the pollutants that cause acid rain—sulfur dioxide (SO2) and nitrogen oxides (NOx)—do damage human health.
• Air pollution like sulfur dioxide and nitrogen oxides can cause respiratory diseases, or can make these diseases worse. Respiratory diseases like asthma or chronic bronchitis make it hard for people to breathe. The pollution that causes acid rain can also create tiny particles.

Answer 2

Answer:

A chemical reaction occurs when sulphur dioxide and nitrogen oxides are released into the air, concluding acid rain. These pollutants can reach high heights in the sky, where they mix and react with water, oxygen, and other molecules to form more acidic pollutants, which are referred to as acid rain.

Explanation:

Causes of acid rain:

• When power plants burn fossil fuels like coal to generate electricity, they release the bulk of sulphur dioxide and a significant amount of nitrogen oxides.
• When coal and oil are burned lots of these gases are released into the atmosphere. Once in the atmosphere, these chemicals react with atmospheric water molecules to generate mild sulfuric and nitric acids in the presence of sunshine.
• The burning of fuel in trucks, vehicles, planes, and buses. On a regular basis, these autos emit substantial levels of sulphur and nitrogen gaseous pollutants into the environment.
• Acid-producing gases, primarily sulphur, are released by volcanoes, resulting in higher-than-normal levels of acid rain.
