Periglacial processes

Periglacial processes refer to the natural activities that occur in regions adjacent to glaciers and ice sheets, where the climate is cold but not permanently frozen. These processes involve the freeze-thaw cycle, which causes ground and rocks to crack, break apart, and move over time. As temperatures fluctuate, ice forms and melts, shaping the landscape through features like patterned ground, solifluction (slow soil flow), and frost heaving (rocks pushed up). These processes significantly alter the terrain, creating distinctive landforms in cold climates without the presence of permanent ice sheets.
