Goal 1

Compare continental and alpine glaciers

• Continental Glaciers

– Near poles

– Moves outwards from center

– Snow accumulation

– Plastic / flow

• Alpine Glaciers

– Mountain tops

– Moves down valleys

– Snow accumulation

– Plastic / flow

– Alpine glacial formations

Goal 2

Recognize and describe the formation of glacial landform

features

• Glacial Plucking, Striations and Grooves

• Terminal Moraine– Till deposits– End

• Lateral Moraine– sides

• Ground moraine

• Outwash

• Drumlins

• Eskers

• Kettle Lakes

• U-shaped valley

NOT u-shaped

• A v-shaped valley for comparison
