What are the sample expository paragraphs about the natural phenomenon of acid rain?

Acid rain is a phenomenon where rainwater has a pH lower than 5.6 (the average pH of natural rainwater), meaning the rain becomes acidic. The primary cause of acid rain is pollution from substances like sulfur dioxide (SO2) and nitrogen oxides (NOx), released from industrial activities and transportation. These chemicals combine with water vapor in the atmosphere to form sulfuric and nitric acid. When it rains, these acids dissolve in the rain and fall to the ground.

Writing expository paragraphs about the natural phenomenon of acid rain is practiced by students in the 8th-grade Literature curriculum.

Students may refer to the following sample expository paragraphs about the natural phenomenon of acid rain:

Sample expository paragraphs about the natural phenomenon of acid rain

Essay 1: Acid Rain – The Invisible Enemy of the Environment

Acid rain, a human-induced natural phenomenon, is becoming a serious threat to the environment. Pollutants like sulfur dioxide and nitrogen oxides from factories and transportation vehicles are released into the atmosphere, where they combine with water vapor to form acids. The rain carries these acid particles down to the earth, polluting water sources, and soil, damaging constructions, and negatively impacting ecosystems.

Essay 2: Causes of Acid Rain Formation

The main causes of acid rain are industrial activities and transportation. Thermal power plants and chemical production facilities emit large quantities of sulfur dioxide and nitrogen oxides. Emissions from cars and motorcycles also significantly contribute to the increased concentration of these pollutants in the air. When these pollutants combine with water vapor in the atmosphere, they form sulfuric and nitric acids, resulting in acid rain.

Essay 3: The Harmful Effects of Acid Rain

Acid rain causes numerous severe damage to the environment and humans. It pollutes water sources, soil, and harms aquatic and terrestrial life. Acid rain also deteriorates air quality, causing respiratory diseases in humans. Additionally, it corrodes constructions, and monuments, leading to substantial economic losses.

Essay 4: The Impact of Acid Rain on Human Life

Acid rain not only harms the environment but also directly affects human health. Acid particles in rain can enter the body through the respiratory tract, causing lung diseases like asthma and bronchitis. Furthermore, acid rain pollutes drinking water sources, leading to skin and digestive diseases.

Essay 5: Solutions to Mitigate Acid Rain

To mitigate the damage caused by acid rain, we need comprehensive and long-term solutions. These include: reducing emissions from factories and vehicles; developing clean energy sources; forestation; treating wastewater before discharging it into the environment; and raising community awareness about environmental protection.
