Morphology

snow + line

The meaning is directly compositional: 'snow' (the frozen precipitation) combined with 'line' (a boundary or dividing mark) yields the boundary above which snow persists. This conceptual 'imaginary line' is a transparent, cross-linguistic way to describe an elevation limit, so a B1 learner who knows the constituents will readily infer the MWE meaning.

Etymology

The noun snow line names the invisible border or line on a mountain where snow stays all year. So, it means the height 'above which snow remains on the ground'.
