2. Regelation - Wikipedia

   en.wikipedia.org/wiki/Regelation

   Regelation is the phenomenon of ice melting under pressure and refreezing when the pressure is reduced. This can be demonstrated by looping a fine wire around a block of ice, with a heavy weight attached to it. The pressure exerted on the ice slowly melts it locally, permitting the wire to pass through the entire block.

3. Snow - Wikipedia

   en.wikipedia.org/wiki/Snow

   Ice dams on roofs form when accumulated snow on a sloping roof melts and flows down the roof, under the insulating blanket of snow, until it reaches below freezing temperature air, typically at the eaves. When the meltwater reaches the freezing air, ice accumulates, forming a dam, and snow that melts later cannot drain properly through the dam ...

4. Glacier ice accumulation - Wikipedia

   en.wikipedia.org/wiki/Glacier_ice_accumulation

   Glaciologists subdivide glaciers into glacier accumulation zones, based on the melting and refreezing occurring. [1] [2] These zones include the dry snow zone, in which the ice entirely retains subfreezing temperatures and no melting occurs. Dry snow zones only occur within the interior regions of the Greenland and Antarctica ice sheets.

   Melt Forms (MF) – Range from clustered round grains of wet snow through melt-freeze rounded polycrystals when water in veins freezes to loosely bonded, fully rounded single crystals and polycrystals.to polycrystals from a surface layer of wet snow that refroze after having been wetted by melt or rainfall. Ice Formations (IF) – Encompass the ...

8. Frost heaving - Wikipedia

   en.wikipedia.org/wiki/Frost_heaving

   Photograph taken 21 March 2010 in Norwich, Vermont. Frost heaving (or a frost heave) is an upwards swelling of soil during freezing conditions caused by an increasing presence of ice as it grows towards the surface, upwards from the depth in the soil where freezing temperatures have penetrated into the soil (the freezing front or freezing boundary).
