Select the description that most closely matches subglacial sediment.
Question 1options:
a glacier within, especially sediment carried within the glacial ice
on the surface of the glacier
in front of a glacier
beneath a glacier

Select the description that matches the term “continental glacier”.
Question 2options:
glacier that covers a significant part of a continent and has an area of at least 50,000 km2
a long-lasting body of ice on land that moves under its own weight
a glacier formed in a mountainous region and confined to a valley
an open fissure on the surface of a glacier

Which of the following descriptions most closely matches the glacial feature called a col?
Question 3 options:
a rocky peak that extends above the ice level of a continental glacier
the low point or pass along a ridge between two glacial valleys
a peak that has been eroded on at least three sides by glaciers
a glacial valley created by a tributary glacier which does not erode as deeply as the main-valley glacier that it joins

The end of the Cryogenian glaciations coincides with the evolution of relatively large and complex life forms on Earth.
Question 4 options:
True
False

There were three major glaciation periods during the Phanerozoic. Which of the following is not one of these three?
Question 5 options:
Huronian
Andean/Saharan
Karoo
Cenozoic

Crevasses form because the upper ridge of ice on a glacier is viscous and able to flow over irregularities.
Question 6 options:
True
False

Select the description that most closely matches supraglacial sediment.
Question 7 options:
within a glacier, especially sediment carried within the glacial ice
on the surface of the glacier
in front of a glacier
beneath a glacier
Ablation till differs from lodgment till because lodgement till is a mixture of fine and coarse angular rock fragments.
Question 8 options:
True
False

Select the description that matches the term “zone of ablation”.
Question 9 options:
the granular transitional state between snow and ice within a glacier
the part of the glacier where there is net gain of ice mass because not all of the snow that falls each winter is able to melt during the following summer
the part of a glacier where there is net loss of ice mass due to melting and calving
an open fissure on the surface of a glacier

Which of the following descriptions most closely matches the glacial feature called a glacial groove?
Question 10 options:
a lake within a rock basin
Lake that occupies a glacial valley
the steep end of a ridge that has been eroded by a main-valley glacier
a straight line created on a rock surface by erosion by a rock fragment embedded in the base of glacial ice

The edges of a glacier move more slowly than the middle of the glacier.
Question 11 options:
True
False
