Acid rain occurs due to the oxidation of : 

1. Carbon, sulphur (unsaturated hydrocarbon) and nitrogen.

2. Ethanol.

3. Methanol.

4. Methane.

Acid rain is due to an increase in the atmospheric concentration of : 

1. Ozone, and dust

2. $C{O}_{\mathrm{2,}}$ and CO

3. $S{O}_{\mathrm{3,}}$ and CO

4 $S{O}_{\mathrm{2,}}$ and $N{O}_2$

Acid rain occurs due to the presence of : 

1. $S{O}_2$ in the atmosphere

2. $N{H}_3$  in the atmosphere

3. $C{O}_2$  in the atmosphere

4. $N_{2}O$  in the atmosphere

An incorrect statement regarding acid rain is that: 

1. It is formed due to the reaction of \(SO_{2}\) and \(NO_{2}\) with rainwater.

2. It causes no damage to monuments like the Taj Mahal.

3. It is harmful to plants.

4. Its pH is less than 5.6

2. Ozone layer pollution.

3. Air pollution.

4. Troposphere pollution.

When rain is accompanied by a thunderstorm, the pH value of the collected rain water is :

1. Dependent upon the amount of dust in the air.

2. Slightly lower when rainwater is without a thunderstorm.

3. Slightly higher when the thunderstorm is not there.

4. Unaffected by the occurrence of thunderstorms.
