Be able to explain/predict how glaciers in different areas respond to climate change due to increased temperatures, more precipitation, feedback mechanisms-A glacier has a mass budget but also MOVES = glacier dynamics – transport of ice from accumulation zone to ablation zone-Be able to explain how the driving stress is derived andpredict how changes to the glacier will affect driving stress-Why glacier ice is described as a visco-plastic material-For each type of glacier movement (basal sliding or internal deformation/creep) be able to describe/explain/draw diagrams to show:oHow it worksoWhat type of glacier it will occur in and whyoThe factors that affect how fast the movement will be in each caseFrom Lecture 18 - Glacier Dynamics-Be able to draw/explain/identify on diagrams:othe movement due to basal sliding othe movement due to internal deformation ozone of plastic flow and zone of rigid flowowhere the fastest flow speed will occur-Be able to make predictions about how bed softness and bed roughness will affect glacier speed and thickness-Be able to describe/explain how water is supplied to the base of a glacier how and predict/draw/interpret graphs of how glacier speed changes over timeFrom Lecture 19 – Surges, tidewater glaciers and ice shelves-Be able to explain why ice shelves are important when considering sea level rise-Icebergs – be able to explain how they form, how they move and how/why they are monitored. Be able to explain and use Archimedes Law to explain what percentage of an iceberg is above and below seawaterFrom Lecture 20 – Glacial landscapes-Be able to explain how glaciers are able to erode the landscape-Be able to explain how the following landscape features form due to glacial erosion and identify them from photos/diagrams: opolished surfaces and striations (冰里有岩石碎片像砂纸)oroche moutonees (冰带起岩石碎片,不对称bedrockoU-shaped valleys and fjords fill with ice extensive erosionerosiono
