Acid rain is precipitation (rain, snow, sleet, or fog) that contains high levels of sulfuric acid (H₂SO₄) and nitric acid (HNO₃). It forms when sulfur dioxide (SO₂) and nitrogen oxides (NOₓ) react with water vapor in the atmosphere. Effects of Acid Rain: Environmental Damage: Acid rain lowers the pH of soil and water bodies, making … Read more
Air pollutants come from both natural and human-made sources. Natural Sources: Volcanic eruptions release sulfur dioxide (SO₂) and particulate matter, which contribute to acid rain and respiratory issues. Forest fires produce carbon monoxide (CO), carbon dioxide (CO₂), and fine particulate matter that cause air pollution. Dust storms, plant pollen, and decaying organic matter also release … Read more
Troposphere: Composed of nitrogen, oxygen, carbon dioxide, water vapor, and trace gases. It is where weather changes occur. Stratosphere: Contains nitrogen, oxygen, and ozone. The ozone layer is located in this layer, which absorbs harmful UV radiation. Related Questions: List two main sources of acid rain. List four human activities that contribute to air pollution. What is … Read more
In the troposphere, temperature decreases with altitude because the Earth’s surface absorbs heat from the sun and warms the lower layers of air. In contrast, in the stratosphere, temperature increases with altitude due to the presence of the ozone layer, which absorbs ultraviolet radiation and converts it into heat. Related Questions: List two main sources … Read more
The atmosphere is the layer of gases surrounding the Earth. It is composed mainly of nitrogen (78%) and oxygen (21%), along with trace amounts of other gases such as carbon dioxide, argon, and water vapor. The atmosphere plays a crucial role in supporting life by regulating temperature, providing oxygen for respiration, and shielding the Earth … Read more
Automobiles contribute to air pollution by emitting carbon monoxide (CO), nitrogen oxides (NOₓ), and hydrocarbons. These pollutants contribute to smog formation, acid rain, and global warming. The burning of gasoline and diesel also releases carbon dioxide (CO₂), a greenhouse gas that enhances climate change. Related Questions: List two main sources of acid rain. List … Read more
The ozone in the stratosphere is essential for life on Earth because it absorbs the sun’s harmful ultraviolet (UV) radiation. This protection prevents skin cancer, cataracts, and other health issues in humans while also shielding ecosystems and agricultural crops from UV damage. Related Questions: List two main sources of acid rain. List four human activities … Read more
Burning of fossil fuels for transportation, electricity generation, and industries. Deforestation, which reduces the absorption of carbon dioxide. Agricultural activities, including the use of chemical fertilizers and pesticides. Industrial processes that release harmful gases like sulfur dioxide, nitrogen oxides, and carbon monoxide. Related Questions: List two main sources of acid rain. What is the importance … Read more
The two main sources of acid rain are: The burning of fossil fuels, such as coal and oil, which releases sulfur dioxide (SO₂) into the air. Vehicle emissions and industrial processes, which release nitrogen oxides (NOₓ) into the atmosphere. Related Questions: List four human activities that contribute to air pollution. What is the importance … Read more
