APSC 151- Glaciation Exam | Questions & Answers (100 %Score) Latest Updated
2024/2025 Comprehensive Questions A+ Graded Answers | With Expert Solutions
what is a glacier - thick mass of ice that originates on land
what is firn - recrystallized dense snow
what is glacial ice - firn that has fused together
what is internal deformation - deformation from pressure that occurs inside the ice

how does meltwater move glaciers - acts like a hydraulic jack to lift and push ice forward
what is soft bed deformation - water-saturated sediment that deforms under a glacier
what is the zone of fracture - the upper 50 m of a glacier, where tension causes crevasses for form in
brittle ice
what is a surge - the rapid movement of a glacier
what is the budget of a glacier - balance between accumulation and loss
what is the zone of accumulation - where a glacier forms
what is the zone of ablation - where there is a net loss of glacier
