Geomorphological processes: weathering (frost action, nivation), ice movement (internal deformation, rotational, compressional, extensional and basal sliding), erosion (plucking, abrasion), transportation and deposition
Glaciers shape the land through a chain of linked processes. These range from frost breaking up rock, to ice moving and grinding across the landscape, to depositing debris when the ice melts.
Real World
Striations (scratches) left by abrasion are visible on exposed bedrock in Snowdonia, Wales, providing geologists with direct evidence of the direction ice flowed during the last glacial period.
Exam Focus
For 'explain' questions on erosion, state the process name, the mechanism, and its landform outcome in sequence to secure full marks.
