Glacier:
Any large
mass of ice
that moves
slowly over
land
VALLEY GLACIER:
CONTINENTAL GLACIER:
Valley Glacier:
A long, narrow
glacier that forms
when snow and
ice build up in a
mountain valley
-
Found on
high
mountains
-
Stay in
valley/follow
valley
Continental
Glacier:
A glacier that
covers much
of a continent
or large island
-
Larger than
valley
glaciers
-
Spread out
in all
directions
Ice Ages:
Times in the
past when
continental
glaciers
covered large
parts of
Earth’s
surface


Form where more
snow falls than melts

Pressure compacts
snow into ice

Gravity pulls glacier
downhill
PLUCKING

The process by which a
glacier picks up rocks as it
flows over the land
ABRASION

Rocks stick to the bottom
of glacier, scrape across the
land, and scratch bedrock
Till:
The sediment
deposited by
a glacier
Fjord:
A glacial
valley filled
with
seawater
Erosion

Horn:
A sharpened
peak on top
of a
mountain –
glaciers have
carved away
the sides

Forms when
melting ice
forms a

till and it fills
with water
No water =
