Acid Rain is mixture of oxides of sulphur and nitrogen, causing a great harm to non-living things.
In non-living things we have so many elements that gets directly affected by acid rain like forest, land, soil.
Soil is a major factor of production especially in India where a large number of people are dependent on agriculture, so this rain adversely effects the soil and thus causes its erosion.
Water which is the only source of living alive gets polluted due to this rain. Actually this occurs due to the activities of human being also as whatever activities we are performing, we should consider that environment doesn't get polluted at all, as only because of such things, these gases are formed in form of clouds and pours down on the earth in form of rain making it acidic in nature.
Due to natural factors also acid rain is formed but to reduce this we can try at our level as nature is the gift of God and its our duty to conserve it.
