L'action gel-dégel.- L'effet du gel et du dégel sur la fragmentation et la désagrégation des roches est très important. C'est le facteur principal de l'altération dans les pays froids et en haute montagne. Il se manifeste dans nos régions par les pierres gélives. L'eau pénètre dans les fissures ou les pores de la roche. Son augmentation de volume, au cours du gel, fait bâiller les joints et désagrège les cristaux [...]. On découvre un optimum de porosité et une augmentation de la désagrégation avec la rapidité des alternances gel-dégel. 3, record 1, French, - action%20gel%2Dd%C3%A9gel
