Cenozoic Ice Age.
a) True *
b) False
2) At what latitudes do glaciers become less common?
a) above 50 degrees N. latitude
b) below 50 degrees N. latitude *
c) 90 degrees N. latitude
d) 60 degrees N. latitude
3) Many of the world’s glaciers lie in two major clusters on the Eurasian landmass. These
clusters are:
a) Caucasus Mountains and Altay Mountains
b) Carpathian Mountains and Black Mountains
c) Norway and Scandinavian Mountains
d) European Alps and south-central Asian zone *
4) What are hillsides that have been cut off by a glacier straightening the valley course
called?
a) hanging valleys
b) truncated spurs *
c) glacial troughs
d) fjords
5) Tributary glaciers do not erode the bedrock as deeply as the main glacial valley;
therefore, when ice melts the tributary valley floor sits at a higher elevation and
produces a _____ above the main valley’s floor.
a) hanging valley *
b) truncated spur
c) glacial trough
d) fjord
6) The weight of glaciers carve out amphitheater-like basins producing _____ high up in a
mountain.
a) cirques *
b) horns
c) aretes
d) rock steps
7) A _____ is a post-glacial feature produced when bedrocks fracture making them
susceptible to frost wedging. The repeated mechanical breakdown of rocks from freezethaw cycles produce bedrocks to produce flat surfaces of varied heights.
a) cirques
b) horn
c) aretes
d) rock steps *
8) All are erosional features of glaciers EXCEPT:
a) moraines *
b) cirques
c) aretes
d) horns
9) _____ are formed when small circular lakes occur at the floor of cirque basins.
a) finger lakes
b) tarns *
c) valley train
d) landslide lake
10) Glacial deposits that have been deposited at the front of glaciers after being pushed
along by a glacier is called:
a) lateral moraines
b) medial moraines
c) ground moraines
d) terminal moraines *
