FIRN Meaning and
Definition
-
Firn is a noun that refers to a specific type of granular ice consisting of densely packed snow grains that have been compacted over time. It is commonly found in high-altitude areas, such as glaciers and ice sheets. Firn is an intermediate stage in the process of snow compaction, occurring before the transformation into solid ice.
The formation of firn begins with fresh snowfall accumulation on the surface. Subsequent snowfall compresses the underlying snow layers, causing compaction. As time passes, the layers become denser and the air is squeezed out, resulting in a metamorphosis of the snow into firn. This process generally takes several years or decades depending on the climate conditions and the thickness of the snowpack.
Firn is characterized by its distinct granular texture, as the individual snow grains are partially fused together. These grains are typically smaller than those found in freshly fallen snow, with a diameter ranging from 1-2 millimeters. Firn is often observed to have a slightly compacted appearance, with a clear distinction between layers, similar to the growth rings found in trees.
Firn plays an essential role in the preservation and formation of glaciers, as it acts as a transition between fresh snow and solid ice. Eventually, with further compaction and the expulsion of remaining air, firn gradually transforms into solid glacial ice.
