Explanation

Acid rain is mainly caused by emissions of Sulfur dioxide and Nitrogen oxide in the atmosphere.

Acid rain mainly Causes health problem like Asthma.

Explanation

• Argon (Ar) is a noble gas that is not typically associated with acid rain.

Acid rain is caused by the presence of pollutants in the air, such as:

• Sulfur dioxide (SO2)
• Nitrogen oxides (NOx)
• Oxygen (O2) plays a role in the formation of acid rain, as it reacts with SO2 and NOx to form acidic compounds.

Explanation

Ozone (O3) is a gas found in the stratosphere.

A stratosphere layer of the atmosphere that extends from about 12 to 50 kilometers (7.5 to 31 miles) above the Earth's surface.

The ozone layer, also known as the ozonosphere.

Explanation

Oxygen (O2) is not a greenhouse gas.

Greenhouse gases are gases in the Earth's atmosphere that absorb and emit radiation, trapping heat and contributing to the Greenhouse Effect.

The main greenhouse gases are:

• Carbon dioxide (CO2)
• Methane (CH4)
• Nitrous oxide (N2O)
• Water vapor (H2O)
• Ozone (O3)
• Chlorofluorocarbons (CFCs)
• Hydrofluorocarbons (HFCs)
• Perfluorocarbons (PFCs)
