GLACIAL LANDFORMS INDICTIVE OF FLOW DIRECTION

roche moutonnee

asymmetrical hill of exposed bedrock; gently sloping uphill side (stoss side) that is polished by abrasion; abrupt steep downhill side (lee side) where the glacier plucked rock pieces

plucking

glacial flow loosens and lifts rocks from glacier bed

Drumlins

smooth, streamlined, tear drop shaped depositional landforms; steep side face the direction from which the ice advanced; tapered end points down glacier

terminal moraine

eroded debris dropped at glaciers farthest extent

recessional moraine

end moraines formed when glacier temporarily stabilized during its retreat
