-periglacial landforms, wich includes gelifraction
landforms (escarpments, cascades, residual slopes, residual ridges, debris slopes), crionival landforms (crionival funnels and channels), nivation landforms (nival niches, often occupied by lakes) and solifluidal landforms (mounds and terraces, sliding rocks), especially developed in Barlea massif area;
Le long des cotes du golfe du Saint-Laurent, du detroit de Northumberland et de la baie de Fundy, des roches friables, de l'activite glaciotectonique, de la gelifraction
et de l'erosion cotiere ont donne lieu a de nombreuses petites ruptures et au recul graduel des falaises cotieres.
Certainly such activities are a crucial precursor of soil formation, and mechanical processes active in cold environments--such processes as gelifraction
, haloclasty and ground ice, have profoundly changed and made angular the divides in such areas.
