Glacial Geomorphology - Coggle Diagram

- - - - Form when alpine glaciers coalesce and spread out over lowland at the base fo mountain ranges
      - Example: Malaspina glacier
    - - Tend to imnundate underlying topgraphy, but tall mountain peaks may protrude through the ice
  - - - Snow depth
      - Snow density
      - Tracking movement
      - Remote sensing
- - - - Amphitheater-shaped depressions formed by glacial abrasion, plucking and frost shattering
  - - - Develop over stagnant ice at glacier margins. Uneven melting creates rolling topography characterized by till ridges interspersed with shallow basins known as kettle lakes.
  - - - Beyond the glacier terminus, sand and gravel depostied within proglacial streams form bars, splitting the stream into multiple small channels.
    - - finer sediments such as silt and clay are transported by meltwater and settle on the bottom of proglacial lakes.
- - - - Upsream side
      - Downstream side
      - Involvling the removal of large rock blocks from the glacier bed. This occurs when a glacier flows over bedrock obstacles
    - - Glaciers use rock clasts at their base as cutting tools to grind and erode the bedrock substrate
  - - - Withinh the glacier, debris is carried downward and provides new abrasive materal at the glacier bed, facilitating bedrock abrasion
  - - - Melting glacier ice releases englacial and subglacial debris. results in the accumulation of glacial till beneath and around glacier
    - - Lodgement occurs when drag forces are insufficient to overcome friction between a rock clast and the glacier bed. The clast comes to rest on the glacier bed, contributing to the formation of glacial deposits
