How does acid rain form and what are its effects?

Acid rain is caused by volcanic eruptions releasing carbon dioxide into the atmosphere.

Acid rain forms when rainwater absorbs excess oxygen from the air, making it acidic.

Acid rain is a result of natural processes like plant respiration and has no significant effects.

Acid rain is formed from the reaction of sulfur dioxide and nitrogen oxides with water vapor in the atmosphere, leading to harmful effects on ecosystems, buildings, and human health.
