QUIZZES // Glacial depositional landforms - drumlins

Q1. Which of these is or are formed in a deposition process environment?


Chatter marks



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?





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


Compressive flow

Subglacial sediment deformation

Q9. In which parts of the British Isles would you not find large drumlin fields?


South-west England

Northern England


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
