Question

how do acid rain cause?​

Answer 1

Answer:

when fossil fuel such as coal and petroleum burns, oxides of sulphide and nitrogen produce. These oxides goes to the atmosphere and combines with water to produce acids which comes down with the rain. This rain is called acid rain.

Hence acid rain is caused by burning of fossil fuels.

Answer 2

Answer:

First to know about the acid rain we should know about the water cycle it is so simple to explain.

Water Cycle:

( 1 ) It starts with the water in the sea

( 2 ) The water level raises and then due to humidity the water

       in the sea  gets evaporated.

( 3 ) After all this the the evaporated water reaches the sky.

( 4 ) The water due to coolness the water above the sky turns

      into cubes.

( 5 ) The ice cubes melt resulting us the rain.

So, acid rain occurs when the pH value of water is less then 5.

the water in acidic nature raises and travel to the sky which

results us the acid rain which is very dangerous.
