Morphology
The compound is directly compositional: a B1 learner who knows 'acid' (something with low pH) and 'precipitation' (rain, snow, etc.) can infer it means precipitation that is acidic. This noun+noun combination follows a common descriptive pattern and is cross-linguistically transparent, so the overall meaning is predictable from the parts.
Etymology
The term acid precipitation comes from the idea of acid, meaning harmful chemicals in the air, joining precipitation like rain or snow and falling to the ground. So it means 'rain or snow that is more acidic than normal and can damage forests, lakes, and buildings'.
