GEOG 203 Final Exam Questions With
100% Correct Answers
Glaciers - answer✔Glaciers play a huge role in shaping the landscape. They are the most
effective erosional agent on the Earth.
Glacial Erosion - answer✔A mechanical action performed by glaciers.
Erosion - answer✔Removal and subsequent transport and deposition of sediments across the
landscape.
Glacial Landforms - answer✔Natural features of Earth's surface shaped the landscape.
Erosional Landforms - answer✔Erosional Landforms are the result of the Glacial erosion
(Example: Cirque); its a landform shaped by whats left after the glacier has eroded sediments
away.
Depositional Landforms - answer✔Depositional Landforms are the result of deposits made by
glaciers (example: moraine); Its a landform created by the material that was eroded by glaciers
and deposited to form a new landform.
Proglacial Lake - answer✔Lake located in front of a glacier formed by melting of ice during
summertime.
Iceberg - answer✔Chuck of ice that was detached from a glacier and floats in water.
Alpine Glacier - answer✔Glaciers that are geographically constrained to mountain ranges and
their valley, they are considered regular glaciers.
Ice Sheets/Continental Glaciers - answer✔Are huge continental ice blocks. Ex- Antartica &
Greenland
Ice Sheets are not constrained by topography: They are "Sheets" of Ice that cover large amounts
of land (>50,000 km2)
Ice Formation - answer✔1) Snowflake-> Falls on top of snow
2) Granular Snow (or neve)-> more dense snow that is created after many months: everyday,
snow thaws during daytime because of sunlight, and freezes at night; over time the snow
becomes more dense
3) Firn-> after ~1 year, neve becomes Firn (when a complete summer and winter cycle has been
completed) and the neve has compacted to become icy because of increasing pressure from snow
and neve accumulating above
4) Glacial Ice
Glaciers and Ice sheets apply tons of weight and pressure to the ground underneath.
Ice Flow - answer✔Dues to pressure applied to the bottom layer of ice, it will begin to melt a
little bit, causing glacier flow slowly (Like a viscous liquid)
3 Zones:
1) Zone of Accumulation
2) Firn Limit
3) Zone of Ablation
If accumulation> ablation Glacier grows and moves downward.
If ablation> Accumulation glacier seems to shrink back up the mountain
If Ablation= Accumulation, the size will remain unchanged
Basal Sliding - answer✔Ice flow only for warm glaciers, AKA Alpine glaciers
