What Glaciated Landscapes covers

Glaciated Landscapes is examined in Component 1 Section A, if glaciated is the landscape you sit. It covers the glacier as a system: inputs, outputs, stores and transfers, the glacial budget, mass balance and feedback, the Quaternary Ice Age and the Little Ice Age, cold-based and warm-based glaciers, glacier ice movement and types of flow, types of ice mass and their distribution, freeze-thaw weathering and glacial erosion processes, factors affecting the rate of glacial erosion, cirques, arêtes and pyramidal peaks, glacial troughs, ribbon lakes, hanging valleys and truncated spurs, roches moutonnées, crag and tail and striations, glacial and fluvioglacial transport, till and types of moraine, drumlins and lowland glacial deposition, ice-contact fluvioglacial landforms, proglacial landforms: sandurs, varves and kettle holes, glacial landscape suites and change over time, periglacial ground ice and permafrost features, periglacial weathering, mass movement, water and wind and glacial landscapes and human activity.

  • Abrasion vs Plucking

    Abrasion: scouring the bedrock with debris held in the ice. Plucking: tearing whole jointed blocks away after refreezing.

Questions from this topic

Each one with the model answer underneath.

  1. 1

    Why is a glacier described as an open system?

    Model answer

    A glacier exchanges both energy and matter with its surroundings. Snow and rock debris enter it and meltwater and sediment leave it.

  2. 2

    Name the main inputs of mass to a glacier.

    Model answer

    Direct snowfall is the largest input to most glaciers. Avalanches from valley sides, wind-blown snow and rockfall debris add further material.

  3. 3

    What are the energy inputs to a glacial system?

    Model answer

    Solar radiation, geothermal heat from the bedrock and the potential energy of ice held at altitude are the energy inputs. Friction at the bed converts some of that potential energy into heat.

  4. 4

    List the main outputs from a glacier.

    Model answer

    Meltwater, calved icebergs, water vapour lost by sublimation and deposited sediment are the outputs. All are grouped together as ablation.

  5. 5

    Define ablation.

    Model answer

    Ablation is the total loss of mass from a glacier by any process. The processes involved are melting, sublimation, calving and wind erosion of snow.

  6. 6

    Define accumulation.

    Model answer

    Accumulation is the total gain of mass by a glacier. Snowfall, avalanche and wind-blown snow are the main contributors.
