When a glacier moves, it picks up and carries the rocks with it. These rocks are weathered by:
abrasion
exfoliation
thermal expansion
hydrolysis
The elongated hills labeled R are most useful in determining the
age of the glacier
direction of movement of the glacier
size of the glacier
velocity of the glacier
A U-shaped Valley is formed by a-
River
Wind
Glacier
Rainfall
U shaped valleys are created by
glaciers
gravity
wind
water

sorted and layered
sorted and not layered

terminal moraine
outwash plain
drumlin
kettle lake
Large boulders that are deposited by melting glaciers
glacial erratics
drumlins
moraines
glacial till
An elongated hill of glacial sediment
drumlin
moraine
outwash plain
Drumlins are useful in determining
direction the glacier moved
how thick the glacier was
how fast the glacier moved
the age of the glacier
The photograph shows scratched and grooved
bedrock with boulders on its surface. The scratches and grooves were most likely created when
alternating thawing and freezing of water cracked the bedrock
flooding from a nearby lake covered the bedrock
a glacier dragged rocks over the bedrock
rocks from a landslide slid along the bedrock
The cross sections show a three-stage sequence in the development of a glacial feature. Which glacial feature has formed by the end of stage 3?
kettle lake
finger lake
drumlin
parallel scratches
