Question

When sulfur emitted by smokestacks combines with moisture in the atmosphere to form acids that are spread by the wind, ____ results.

a. wet pollution
b. air pollution
c. acid rain
d. fire
e. emissions

Answer 1

The correct option is: c. acid rain

Step-by-step explanation:

Acid rain refers to the precipitation that has an acidic pH. This type of precipitation is harmful as it has high hydrogen ion concentration.

The harmful emissions such as sulfur dioxide and nitrogen oxide, that are present in the Earth's atmosphere and transported by the air and wind, react with the water molecules during the precipitation to produce acidic rain.
