Quizplus · Accepted Answer

The construction of different shapes of periglacial rock and soil debris within the periglacial zone is known as patterned ground, which includes various shapes such as circles, polygons, and stripes. Ice-wedge polygons are a specific type of patterned ground that forms due to the repeated freezing and thawing of the ground, while pingos are large, ice-cored mounds that form due to the pressure of expanding frozen ground. Boulder fields are simply areas densely covered in large boulders, and do not necessarily indicate any specific periglacial processes.
