To which does a snowline refer?

Question

Quizplus · Accepted Answer

The snowline refers to the lowest line (latitude or elevation) where winter snow accumulation persists throughout the summer. Option A is incorrect because snowline is not specifically related to latitude but can also refer to elevation. Option B is incorrect because it refers to a specific event in the Earth's history rather than a general concept. Option C is incorrect because an isoline only shows a uniform value of a specific variable and doesn't necessarily refer to the snowline.
