D the slow movement of saturated soil and regolith down a hillslope during the thaw cycle (summer)
E a type of ground formed when soil or rock temperatures remain below 0 degrees centigrade for at least 2 years
F a type of irregular surface topography caused by thermal subsidence and erosion due to ice-wedge melting and poor drainage
End of Question 1


Question 2
2 Match each glacial landform with the appropriate definition.
Using the pull-down menus, match each item in the left column to the corresponding item in the right column.
A a low and rolling area made up of unstratified materials behind an end moraine
B a steep-sided hole filled with water formed by the slow melting of an isolated block of glacial ice
C an asymmetrical hill of exposed bedrock with a sloping upstream (stoss) side and a steep downstream (lee) side
D an accumulation of till streamlined in the direction of ice movement, with the blunt end upstream and the tapered end downstream
E a sinuous ridge of coarse sand and gravel formed along the channel of a stream flowing beneath the glacier
