The pH scale is a scale that measures the amount of acidity in a substance. The scale goes from 1 to 14, 1 being very acidic and 14 being basic. An example of a acid of 1 on the pH scale is gastric acid or stomach acid. An example of 14 on the pH scale is liquid drain cleaner.
One cause of acid rain is the burning of fossil fuels. This is because when fossil fuels are burned they form a sulfur and nitrogen compound that mixes with water vapor. Another thing that causes acid rain is power plants that release sulfur dioxide. The last thing that causes acid rain is exhaust from cars, trains, and trucks.
Acid rain can effect both plant and animal life. It can effect plant life if the plant absorbs water that comes from soil that is chemically changed. This can cause the plant to die slowly. Acid rain can effect animal life if the animal lives underwater and the water is polluted.
Acid rain can be prevented by using less fossil fuels, and instead using different energy resources. Another way acid rain can be prevented is by using less machines that can cause pollution.
