How does solar heating help in fog dissipation?

Answer and explanation

Correct answer: It warms air and increases evaporation of droplets

Answer: C. Fog requires tiny liquid droplets to remain suspended in air. When sunlight warms the ground and the air above it, the air can hold more water vapour. The fog droplets may then evaporate back into invisible water vapour, and the fog becomes thinner or disappears. C is correct because it describes warming and increased evaporation. A is wrong because heating does not turn water droplets into stones. B is wrong because ordinary solar heating does not chemically convert water vapour into oxygen. D is wrong because sunlight does not transform land into sea. Wind mixing can also help disperse fog, but the question asks specifically about solar heating. Memory cue: warming lowers relative humidity and helps fog droplets evaporate.
