BMI stands for Body Mass Index. It is a measure of body composition. BMI is calculated by taking a person's weight and dividing by their height squared. For instance, if your height is 1.82 meters, the divisor of the calculation will be (1.82 * 1.82) = 3.3124.
Sources of Acid Rain. Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain. Sulfur dioxide and nitrogen oxides dissolve very easily in water and can be carried very far by the wind. As a result, the two compounds can travel long distances where they become part of the rain, sleet, snow, and fog that we experience on certain days. Human activities are the main cause of acid rain.
Best Answer: The primary causes of acid rain are sulfur dioxide and nitrogen oxides. These chemicals are released by certain industrial processes. Once the tiny pollutant molecules have entered the atmosphere, they can travel for thousands of miles.cid rain is caused by carbon dioxide making the rain acidic which means that when it raisn it does damage to building works made of stone, espically limestone and will do other damage to nature as well.
