Acid rain is a phenomenon caused by the release of sulphur dioxide (SO_2) and nitrogen oxides (NO_x) into the atmosphere, primarily from industrial processes and transportation. When these gases combine with water vapour and other chemicals in the atmosphere, such as ozone and hydrogen peroxide, they form sulfuric acid (H_2SO_4) and nitric acid (HNO_3), respectively. These acids then dissolve in rainwater or other forms of precipitation, resulting in acid rain.

Therefore, both the assertion and reasoning are correct, and the reasoning correctly explains the assertion.
