The correct answer is geosphere, atmosphere, hydrosphere.
Here's the reasoning:
-
Atmosphere: Human-caused air pollution leads to the formation of acid rain, which directly involves the atmosphere.
-
Geosphere: Acid rain dissolves limestone rocks, which are part of the geosphere.
-
Hydrosphere: Acid rain also falls into bodies of water, influencing the hydrosphere.
The biosphere and cryosphere are not directly influenced in the context of the process described.
