frostsprängning
Från WP:
Frostsprängning är en mekanisk vittring där berget sönderdelas i mindre bitar.
Bland de mekaniska vittringsmekanismerna är frostsprängning den väsentligaste inom jordens kalla regioner och inom fjällområden. Vid frostsprängning tränger vatten in i genom sprickor och porer i berggrunden, den ökar vid frysning till is sin volym. Detta medför att sprickor vidgas och mineralkorn frigörs från berget.
A cryoseism, also known as a frost quake[1][2], may be caused by a sudden cracking action in frozen soil or rock saturated with water or ice.[3] As water seeps down into the rock, it freezes and expands, putting stress on surrounding rock. This builds up until it is relieved explosively in a cryoseism.[4]
Another form of cryoseism known as an ice quake, is a non-tectonic seismic event caused by sudden glacial movements, sometimes due to the formation of a thin veneer of liquid water under a glacier from surface melting. Usually, a glacier would stick to the rough bedrock, but the hydraulic pressure acts as a lubricant, allowing it to slide up to many metres at once.[5][6] This type of cryoseism can last for tens of minutes.[7]
