Acid rain is: dust, soot, and other finely divided solid and liquid particles. a condition associated with smog that causes eye irritation, irritation of the respiratory tract, and chest pains. a mixture of pollutants, principally ground-level ozone. an atmospheric condition during which a warm layer of air stalls above a cool layer. the precipitation of acidic compounds formed when components of air pollution interact with other components in the air.

The correct option is: the precipitation of acidic compounds formed when components of air pollution interact with other components in the air.

Explanation:

Acid rain is a form of precipitation which is usually acidic in nature. The acidic nature of rain is due to the reaction of water molecules with sulfur dioxide, carbon dioxide and nitrogen oxide present in the air, to produce acids.

There are many adverse effects of acid rain, some of them are: effect on water bodies, forests, living organisms, corrosion of structures made of steel and weathering of buildings.

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
