What is the difference between polar and temperate glaciers?

Polar glaciers are primarily found in regions with extremely cold climates, such as Antarctica and Greenland, and they typically exhibit little seasonal melting. They are characterized by their thick ice layers and low temperatures, which can lead to the preservation of ancient ice and features. In contrast, temperate glaciers are located in areas with milder climates and experience significant seasonal melting, resulting in a more dynamic ice flow and the presence of meltwater at their base. This melting and refreezing cycle influences their movement and shape, leading to distinct geological features.
