Adverse effects of acid rain include all of the following except:

  1. accelerated chemical weathering of building materials

  2. damage to forests and crops

  3. damage to aquatic organisms

  4. damage to septic systems
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Acid rains: when the concentrations of oxides of nitrogen and sulphur increases in the air, rain water gets mixed up with these oxides to form acid rains.

Among the given options all are apt for the effects of acid rain except that it causes damage to the septic system.

It cannot cause damage to the septic system because most of the septic systems are underground and polluting such system with acids do not cause any adverse reaction to the environment.

Accelerated chemical weathering of building materials, damage to forests and crops, damage to aquatic organisms are the immediate effects of acid rains
