What is it called when a solid turns into a liquid then back?
In case of Ice or Water it is Known as 'Regelation'
What is regelation and how do ice skaters make use of it?
Regelation is the phenomenon of melting under pressure and freezing again when the pressure is reduced.Skating is possible on snow due to the formation of water below the skates.Water is formed due to the increase of pressure and it acts as a lubricant.
Why are there no trails of the skates on the ice after the ice skater has passed by?
Skating on ice happens through a process called regelation. The blade of the skate exerts pressure downward essentially causing the ice to melt due to the pressure, creating for a short time the little bit of water needed for the skater to move and then as the pressure is gone, that water refreezes usually in the ridges that are typical on a skating rink.
If we put pressure on ice then how can it melt?
When pressure is applied to ice, the melting point decreases. This means that even if the ice is below its normal melting point, the pressure can cause it to melt. This is known as pressure melting or regelation.

What is melting of ice under pressure?
It's called "regelation" and is why ice is slippery to walk on. Solid water is no more slick than any other material, but when walked upon, the downward pressure causes a thin layer of water to liquify at the interface between ice and shoe leather. This liquid layer acts as a lubricant, momentarily reducing the coefficient of friction to nearly zero. Any sudden moves, and down you go!
How do glaciers flow around solid obstacles?
by either, pushing it further into the ground by top forces. or pushing around it because it has already got a rooted path to the ground. however if you mean how can they move objects and make it look like the have left them, then it is simply picking and plucking!Answer:Ice may look like solid (and feel like it when you fall) but it acts as a liquid under many conditions. When pressed against an object it melts a bit and flows out of the way. In the classic physics experiment a wire is stretched over a block of ice and pulled down with two weights. The wire passes through the ice with the ice melting on the downward side and reforming on the upper side.Technically this is referred to as "Regelation", the phenomenon of melting under pressure and freezing again when the pressure is reduced.
What are the two major flow mechanisms in a glacier?
Glaciers can flow by internal deformation. Under this mechanism, the ice deforms due to gravity and ice crystal movement. Ice that has more warmth and thickness will usually deform more rapidly, but the overall movement under this mechanism is very slow.
