The correct answer is: C. Acid rain.
Acid rain is a form of air pollution that occurs when sulfur dioxide and nitrogen oxides are released into the atmosphere and react with water, oxygen, and other chemicals to form acids. These acids then fall to the Earth as rain, snow, sleet, or fog.
Acid rain can cause a variety of problems, including:
- Damage to forests and other vegetation
- Death of fish and other aquatic life
- Corrosion of buildings and other structures
- Acidification of lakes and streams
- Health problems in humans and animals
Aerosols are tiny particles or droplets that are suspended in the air. They can be natural or man-made, and they can come from a variety of sources, including volcanoes, dust storms, and industrial emissions.
Ozone is a gas that is found in the Earth’s atmosphere. It is created when oxygen molecules are split by ultraviolet radiation from the sun. Ozone is beneficial in the upper atmosphere, where it helps to protect the Earth from harmful ultraviolet radiation. However, ozone in the lower atmosphere can be harmful to human health and the environment.
PAN is a type of air pollution that is formed when nitrogen oxides and hydrocarbons react in the presence of sunlight. PAN is a major component of smog, and it can cause a variety of health problems, including respiratory problems, eye irritation, and headaches.
In conclusion, the correct answer to the question “Soil pollution is caused by” is C. Acid rain. Acid rain is a form of air pollution that occurs when sulfur dioxide and nitrogen oxides are released into the atmosphere and react with water, oxygen, and other chemicals to form acids. These acids then fall to the Earth as rain, snow, sleet, or fog. Acid rain can cause a variety of problems, including damage to forests and other vegetation, death of fish and other aquatic life, corrosion of buildings and other structures, acidification of lakes and streams, and health problems in humans and animals.
