The term "glacial" refers to anything related to glaciers, which are large masses of ice that form from compacted snow over many years. Glaciers are found in polar regions and high mountains, where temperatures remain low enough for ice to persist. The movement of glaciers can shape landscapes, creating valleys and fjords. In a broader context, "glacial" can also describe extremely cold temperatures or conditions. For example, a "glacial breeze" indicates a very chilly wind. This term is often used metaphorically to describe something that is slow-moving or unchanging, similar to the slow flow of a glacier.
