  1. Glaciation & climate change Climatic cycles: we are in a glacial period Climate change: glacial and interglacial Ice sheets: although it does relate to drift geology in London Advance/Retreat, accumulation/ablation (net balance) Glacial budget Inputs: ice, snow & avalanches (relates to weathering) Ice formation Nivation Outputs: evaporation, melting (ablation) & claving Upland (erosional) glaciation Corries, Arêtes, Pyramidal peeks Supra/En /Sub-glacial transport “interpret a range of sources… maps, diagrams, photos & GIS” Glacial transport U-shaped valley (hanging valley, truncated spurs & ribbon valleys) Periglaciation& glacial fringes: Tundra Till, drumlins & morraines Lowland (depositional) glaciation Fluvo-glacial: kames & outwash plains
