Test your knowledge of drumlins and glacial, depositional landforms for A level with this 13-question quiz.
If you haven't already done it, work through the web enquiry on glacial, depositional landforms on the PowerPoint. Or do it again to help fill in any gaps in what you know!
Basal ice layer
The gently sloping, tapering end
The steeper, blunter end
The long axis
The transverse axis
Bowl of bananas topography
Packet of biscuits topography
Basket of eggs topography
Plate of chips topography
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.
Subglacial sediment deformation
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
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.
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.
