Firn densification

Firn densification is the natural process where accumulated snow gradually transforms into dense, compacted ice over time. As new snow falls, it Lies on top of older layers, compressing the lower layers through weight and pressure. This process reduces air pockets, increasing the snow's density until it becomes glacial ice. Factors like temperature, snowfall rate, and ice age influence how quickly firn densifies. Understanding this process is important for studying glaciers and ice sheets, as it helps scientists determine ice thickness, flow, and the history of climate change stored within the ice layers.
