What Is Acid Rain?

Acid gases are produced when fossil fuels like coal and oil are burned in power stations, factories and in our own homes. Acid rain is rain that has been made acidic by certain pollutants in the air. Most of these acid gases are blown into the sky, and when they mix with the clouds it can cause rain - or snow, sleet, fog, mist or hail - to become more acidic. Acid rain is rain that has been made acidic by certain pollutants in the air. Acid rain occurs when these gases react in the atmosphere with water, oxygen, and other chemicals to form various acidic compounds. The result is a mild solution of sulfuric acid and nitric acid. When sulfur dioxide and nitrogen oxides are released from power plants and other sources, prevailing winds blow these

Acid rain can effect trees in several different ways. It can dissolve and wash away the minerals and nutrients in the soil. These factors in the soil help the trees to grow and is very important. Acid rain also cause the release of dangerous substances such as aluminum into the soil. Photosynthesis is also affected because of the waxy protective layer of the leaves being harmed. A combination of these effects weakens the trees which means that they can be more easily attacked by diseases and insects or injured by bad weather. It is not just trees that are affected by acid rain, other plants may also suffer.

The outcomes due to acid rain is most obvious in aquatic habitats. As the acidity in lakes increase, the water becomes clearer and the lives of fish and other water animals decrease. The acidity of the water does not just affect species directly, it also causes toxic substances like aluminum to be released into the water from the soil, harming fish and other aquatic animals. Lakes, rivers and marshes each have their own fragile ecosystem with many different species of plants and animals all depending on one another to survive. If a species of fish disappears, the animals which feed on it will gradually disappear too. If the extinct fish used to feed on a particular species of large insect, that insect population will start to grow, this in turn will affect the smaller insects or plankton on which the larger insect
