QUIZZES // Glacial depositional landforms - drumlins
Q1. Which of these is or are formed in a deposition process environment?
Striations
Chatter marks
Kame
Sichelwannen
Q2. Which of the following process environments are drumlins formed in?
Glacial deposition
Glacifluvial erosion
Glaciolacustrine deposition
Glacimarine deposits
Q3. Drumlin formation occurs in the interaction between the bottom of the glacier and the sediment underlying it. Which of these terms describes that zone?
Supraglacial zone
Englacial zone
Basal ice layer
Subglacial zone
Q4. Which one of these bedforms is the largest?
Flute
Drumlin
Megaflute
MSGL
Q5. Which end of a drumlin shows the down-ice direction?
The gently sloping, tapering end
The steeper, blunter end
The long axis
The transverse axis
Q6. Drumlin fields look like a lot of rounded hummocks over the landscape. Which one of these phrases is often used to describe this landscape?
Bowl of bananas topography
Packet of biscuits topography
Basket of eggs topography
Plate of chips topography
Q7. The elongation index of a drumlin gives information about the speed of ice flow. Which one of the following statements about the elongation index is correct?
A high elongation index indicates faster ice flow
A high elongation index indicates a glacial retreat
A low elongation index indicates faster ice flow
A low elongation index indicates a glacial surge
Q8. Which one of the following describes a process of drumlin formation?
Basal sliding
Calving
Compressive flow
Subglacial sediment deformation
Q9. In which parts of the British Isles would you not find large drumlin fields?
Scotland
South-west England
Northern England
Ireland
Q10. Which of the following describes a jökulhlaup?
Mountain tops that stick up above an ice sheet
A glacial outburst flood
The open sea water between ice on the sea (pack ice) and the land
Volcanoes that erupt beneath glaciers, melting through the ice
Q11. How do sticky spots contribute to drumlin formation?
They resist subglacial water flow which erodes the sediments around them
They are areas of ice compression where ice flow speed decreases, leading to deposition
They are where basal drag is high compared to the surroundings, causing sediment to lodge
They describe parts of the ice which pluck material from the bedrock
Q12. Which one of the following types of substrate (the till under the glacier) do you think is most likely to deform?
Frozen substrate
Impermeable substrate
Saturated substrate
Consolidated substrate
Q13. ‘Drumlins are likely to be polygenetic in nature.’ What does polygenetic mean here?
They are found in a deposition process environment
They are part of a continuum of other bedforms
They are formed by a range of different processes, rather than just one
No one knows how they are formed
