What is acid rain and how does it form? Acid rain, or acid deposition, is a broad term that includes any form of precipitation with acidic components, such as sulfuric or nitric acid that fall to the ground from the atmosphere in wet or dry forms. This can include rain, snow, fog, hail or even dust that is acidic.
Pollutants like sulphur dioxide and nitrogen dioxide liberated into the air by industries reacts with water vapour in air to form sulphuric acid and nitric acid. These acids come down as rain, called acid rain.
Explain why increasing levels of acid rain affects seed growth: Acid rain decreases the pH of the soil, causing its acidity to increase, which decreases the level of important nutrients found in the soil. This process can negatively affect the nutrition and overall growth of crops.
What are the ways we could eliminate this problem? A great way to reduce acid rain is to produce energy without using fossil fuels. Instead, people can use renewable energy sources, such as solar and wind power. Renewable energy sources help reduce acid rain because they produce much less pollution.
