What causes acid rain?
A
High concentrations of sulfuric or nitric acid from pollution
B
Fertilizer use
C
Pesticide use
D
CFCs
Explanation: 

Detailed explanation-1: -Acid rain results when sulfur dioxide (SO2) and nitrogen oxides (NOX) are emitted into the atmosphere and transported by wind and air currents. The SO2 and NOX react with water, oxygen and other chemicals to form sulfuric and nitric acids. These then mix with water and other materials before falling to the ground.

Detailed explanation-2: -When acid rain and dry acidic particles fall to earth, the nitric and sulfuric acid that make the particles acidic can land on statues, buildings, and other manmade structures, and damage their surfaces. The acidic particles corrode metal and cause paint and stone to deteriorate more quickly.

Detailed explanation-3: -Acid rain is the result of increased sulphur and nitrogen oxide levels in the atmosphere. When nitrogen oxides and sulfur dioxide reacts with water, oxygen and other chemicals forms nitric acid and sulfuric acid which then mix with rainwater and causes acid rain.

Detailed explanation-4: -Acid rain comes in many forms: rain, snow, sleet, hail, and fog (wet deposition), and as acid particles, aerosols, and gases (dry deposition). Acid deposition forms when sulfur dioxide (SO2) and nitrogen oxides (NOx) combine with moisture in the atmosphere to produce sulfuric acid and nitric acid.
