2. Glacier: a Flowing Stream of Ice Mountain Continental (Ice Sheets)

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

4. Anatomy of a Glacier

5. Flow Glaciers flow due to Gravity and Internal deformation

6. Crevasse Diagrams

10. A Typical Glacial Advance and Retreat

11. As long as Accumulation = Ablation, the Glacier Front Remains Fixed

12. If Accumulation Exceeds Ablation, the Glacier Advances

13. If Ablation Exceeds Accumulation, the Glacier Retreats

14. Eventually, Material Trapped in the Ice Reaches the Terminus
