  2. Which landforms form when sea level falls relative to the land surface?

    • Submergent landforms
    • Emergent landforms
    • Depositional landforms
    • Erosional landforms

  3. What landform is created when a river valley is flooded by sea level rise?

    • Dalmatian coast
    • Ria
    • Fjord
    • Marine terrace

  4. What shape characterises the cross-section of a flooded glacial valley known as a fjord?

    • Crescent-shaped
    • U-shaped
    • Flat-bottomed
    • V-shaped

  5. What feature is commonly found behind a raised beach on an emergent coastline?

    • Tombolo
    • Barrier island
    • Abandoned cliff
    • Spit

  6. What process occurs when land rebounds upwards following the melting of heavy ice sheets?

    • Isostatic recovery
    • Thermal expansion
    • Marine transgression
    • Eustatic fall

  7. What term describes a flat, step-like coastal platform raised above current sea level?

    • Berm
    • Wave-cut notch
    • Offshore bar
    • Marine terrace

  8. How were many shingle beaches formed during post-glacial sea level rise?

    • Deep ocean dredging
    • Subaerial weathering
    • Landward sediment movement
    • Offshore sediment loss

  9. Kingsbridge estuary in Devon is a flooded river valley. What type of landform is this?

    • Fjord
    • Ria
    • Marine terrace
    • Raised beach

  10. A coastal area displays ancient wave-cut platforms situated twenty metres above current high tide. What landscape is this?

    • Estuarine landscape
    • Submergent landscape
    • Glacial landscape
    • Emergent landscape

  11. What shallow underwater feature is typically found at the mouth of a fjord?

    • Delta
    • Glacial sill
    • Wave-cut platform
    • Sand spit

  12. Which process primarily modifies an abandoned cliff during modern temperate conditions?

    • Marine erosion
    • Subaerial weathering
    • Longshore drift
    • Corrasion

  13. Unlike a ria, a fjord typically features which cross-sectional profile?

    • Symmetrical dune
    • Shallow, V-shaped
    • Gently sloping
    • Steep, flat-bottomed

  14. During a glacial period, why does global eustatic sea level fall significantly?

    • Ice sheet accumulation
    • Crustal sinking
    • Thermal expansion
    • Increased precipitation

  15. Chesil Beach in Dorset is a prime example of which submergent coastal feature?

    • Raised beach
    • Ria
    • Fjord
    • Shingle beach

  16. How will accelerated global warming most directly affect existing rias and fjords?

    • Rapid dune formation
    • Deeper water inundation
    • Uplift into terraces
    • Dessication and drying

  17. What thermal process causes global eustatic sea level rise during interglacial climate periods?

    • Isostatic depression
    • Thermal expansion
    • Salt weathering
    • Thermal contraction

  18. How might future climate change and sea level rise impact lower-lying raised beaches?

    • Isostatic uplift
    • Glacial scouring
    • Complete desiccation
    • Marine re-excavation

  19. High above sea level, an isolated rock pillar stands on dry land near a cliff. What is it?

    • Spit
    • Active stack
    • Tombolo
    • Relict stack

  20. What key difference distinguishes a ria from a fjord in terms of landform origin?

    • Marine versus aeolian
    • Deposition versus erosion
    • Tectonic versus volcanic
    • Fluvial versus glacial
