Glacier Types: Valley vs. Continental

Section role: Supports the 'Synthesizing the Science of Ice Sheets' section while the teacher formalizes the definitions and components of Valley and Continental glaciers. Slides: (1) Title — 'Beyond the Mountain Peak: Types of Glaciers'; (2) Recalling Assumptions — bullets: Briefly revisit common initial ideas about glaciers from Section 1, how 'Mystery Models' in Section 2 challenged these; (3) Valley Glaciers Defined — bullets: Definition as ice flowing through mountain valleys, image of a valley glacier; (4) Valley Glacier Components — bullets: Accumulation Zone (snow buildup), Ablation Zone (melting/waste), Snout (terminal end), labeled diagram of a valley glacier; (5) Case Study: Gangotri Glacier — bullets: Location in Himalayas, visual of its confined path and flow; (6) Continental Glaciers Defined — bullets: Definition as vast ice sheets, image of an ice sheet; (7) Continental Glacier Components — bullets: Accumulation Zone, Snout, emphasis on outward flow and ablation often occurring at sea/surface rather than a distinct 'zone'; (8) Case Study: Antarctica Ice Sheet — bullets: Global significance, visual of its massive coverage and outward flow; (9) Key Differences Summary — bullets: Table or graphic comparing Valley and Continental glaciers on flow direction, typical ablation location, and component naming conventions; (10) Correcting Misconceptions — bullets: Reiterate that not all glaciers have identical zones, addressing the 'origin of the belief' mentioned in the narrative. Closing slide: 'How do our new definitions challenge initial mental images of ice formations?' — sets up critical reflection in Section 4.
