The 20 questions

  1. Which long, winding ridge of stratified sand and gravel is deposited by meltwater streams beneath glaciers?

    • Kame
    • Esker
    • Moraine
    • Drumlin

  2. Which glacio-fluvial landform is a mound of sorted sediment deposited in depressions on stagnant ice?

    • Esker
    • Kame
    • Erratic
    • Corrie

  3. What extensive, flat landform is created by sorted sediments deposited by meltwater beyond a glacier?

    • Outwash plain
    • Roche moutonnée
    • Ribbon lake
    • Till plain

  4. How are glacio-fluvial landforms like eskers modified as post-glacial vegetation establishes on them?

    • Gelifluction
    • Sublimation
    • Gleying
    • Stabilisation

  5. Which process sorts sediment in glacio-fluvial landforms, separating fine material from coarse gravel?

    • Glacial abrasion
    • Frost shattering
    • Ice plucking
    • Fluvial deposition

  6. Which ice-cored periglacial mound relies on hydrostatic pressure from a trapped water body to form?

    • Thermokarst depression
    • Solifluction lobe
    • Open-system pingo
    • Closed-system pingo

  7. Which pingo type forms in discontinuous permafrost where artesian groundwater rises and freezes near the surface?

    • Open-system pingo
    • Closed-system pingo
    • Patterned ground
    • Thermokarst lake

  8. Which periglacial process sorts coarse stones into geometric shapes on gently sloped terrain?

    • Abrasion
    • Gelifluction
    • Frost heaving
    • Nivation

  9. What landform remains after the central ice core of a pingo completely thaws?

    • Ruptured pingo remnant
    • Roche moutonnée
    • Drumlin field
    • Arête

  10. Which mass movement process involves saturated surface soil sliding over impermeable permafrost in summer?

    • Rotational slump
    • Soil creep
    • Rockfall
    • Solifluction

  11. What irregular landscape of marshy hollows forms when permafrost thaws due to climate warming?

    • Patterned ground
    • Outwash plain
    • Thermokarst
    • Erratic field

  12. Why are elevated pile foundations used for buildings constructed in periglacial settlements?

    • Prevent permafrost thawing
    • Promote frost heaving
    • Stop surface flooding
    • Increase wind exposure

  13. How does removing natural vegetation cover in periglacial areas impact the active soil layer?

    • Prevents solifluction
    • Freezes groundwater permanently
    • Increases thawing depth
    • Decreases thawing depth

  14. What immediate change occurs to river sediment supply downstream when a valley dam is constructed?

    • Increased turbidity
    • Sediment surging
    • Sediment trapping
    • Enhanced deposition

  15. Which process increases directly below glacial river dams due to clear, sediment-starved discharge?

    • Channel scour
    • Braid formation
    • Delta growth
    • Aggradation

  16. How do gravel extraction activities in glacio-fluvial landscapes alter original post-glacial landforms?

    • Accelerates freeze-thaw
    • Increases glaciation
    • Destroys stratification
    • Forms pingos

  17. What effect does active layer warming have on slope stability in high-latitude periglacial regions?

    • Stabilises soil matrices
    • Increases slope failure
    • Prevents mass movement
    • Eliminates solifluction

  18. How does post-glacial stream incision modify outwash plains over extended geological timescales?

    • Forms terraces
    • Builds moraines
    • Creates eskers
    • Generates pingos

  19. What thermal impact do heated oil pipelines have when laid directly across permafrost landscapes?

    • Builds pingos
    • Freezes active layers
    • Melts ground ice
    • Prevents solifluction

  20. How does modern climate change affect the rate of physical weathering on post-glacial landforms?

    • Stops river incision
    • Reduces freeze-thaw frequency
    • Eliminates oxidation
    • Increases plucking
