Take-Away Points 1. Glaciers are flowing streams of ice 2. Glaciers have a zone of accumulation where snowfall exceeds losses (ablation) 3. Accumulation can be due to high altitude (mountain glaciers) or cold climate (continental glaciers) 4. Glaciers have a zone of ablation where losses exceed snowfall 5. Glaciers are governed by a balance of snowfall, ice flow, and ablation 6. Glaciers retreat by melting back, not by retracting 7. Glaciers produce distinctive landforms and small scale features

Snowfall vs Melting & Evaporation (Ablation) Zone of Accumulation Snowfall Exceeds Melting & Evaporation Excess Snow Turns to Ice & Flows Out Zone of Melting or Ablation Melting & Evaporation Exceeds Snowfall Melting Excess Made up by Ice Flowing in Terminus of Glacier Snowfall & Inflow = Melting & Evaporation (Ablation)
