Glaciation

This educational film explores the life cycle, movement, and geographical impact of glaciers, tracing their origins from fresh snow crystals in the Canadian Arctic to solid masses of flowing ice. It demonstrates how accumulating snow transforms into granular firn and eventually packs into dense ice that moves under immense pressure, shaping landscapes through processes like erosion, crevasse formation, and the creation of moraines and outwash plains. The narrative also examines how glacial melting and weather patterns affect glacier advancement and recession, ultimately highlighting how ancient ice sheets from the Ice Age profoundly shaped the topography, soil composition, and human settlement patterns of North America.
