WebRegelation is the phenomenon of melting under pressure and freezing again when the pressure is reduced. Many sources state that regelation 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. WebSep 18, 2024 · Michael Faraday first described and named the process of regelation. The process is due to the special nature of hydrogen bonding. When ice is compressed, the O:H (nonbond) distance shortens while the H-O covalent bond elongates and weaken towards O:H. Melting point depression occurs as the H-O bond loses energy.

In addition, meltwater may be transferred along the base of a glacier as a thin sheet.

WebJun 22, 2024 · Glacier beds are rough, not smooth. Bumps in the surface of the glacier bed cause melting on the upstream side, and re-freezing on the downstream side. This is called regelation, and it occurs because pressures mount up behind obstacles to ice flow. Ice melts under pressure, and this lubricates the bed of the glacier. WebBasal sliding occurs when the temperature at the base of the glacier is above pressure melting point (the temperature where ice is on the verge of melting) and so melting can …
