Explore how temperature affects the rate and type of glacier movement. This interactive A-level geography simulation compares warm-based and cold-based glaciers, with close-up views of movement between ice crystals and deformation within individual crystals. Follow moving markers, switch between side and bird’s-eye views, and investigate how temperature and basal water pressure affect internal deformation and basal sliding. Designed to help students connect processes within the ice to the movement of an entire glacier. simopsis
