What Causes Acid Rain?

Acid rain is caused by achemical reaction that begins when compoundslike sulfur dioxide and nitrogen dioxide fly into the air. These compounds can float very highly and move very fast. So after this substances floated to the sky they get mixed with clouds. So now these clouds are contaminated with this acids andthe water that these clouds give are acidic, that is called acid rain.

Human activities are the main cause of acid rain. This means that the humans are the ones who create all this acids that mix with the clouds. The power plants release the majority of sulfur dioxide. Most of the nitrogen oxide is release when

they burn fossil fuels to make electricity. Also all the cars, buses and trucks release acids into the air.
