1. More snowfall than melt: The primary requirement is a consistent surplus of snowfall over melt. This means that the amount of snow accumulating in a given area must exceed the amount lost through melting, evaporation, and sublimation. This allows the snow to accumulate and compact into glacial ice.
2. Sufficiently cold temperatures: The temperatures must be consistently below freezing for extended periods to prevent the snow from melting completely. These frigid temperatures are crucial for the process of snow transforming into ice.
