It is very good question! Water increase in volume as it freezes. Many things can occur there. It will come out of the crack as it starts freezing. Then the remaining water gets freezes. Water freezes inside and create that extra space. Usually it is possible. Here the two parts get little bit separated. If the two parts are rigid and strong, then the freezing point of water can drop greatly and water may not be able to freeze. Else the ice may eventually brake the structure into two or more pieces.
The ice expands in the crack and may split the rock, as will eventually the roots of a plant.
Expansion causes stress, which may induce fractures.
Ice wedging, also called frost wedging or frost shattering is a process where water seeps into cracks in rocks and freezes. Since water expands when it freezes this cpushes the cracks further open, eventually breaking the rock apart.
No, the process of freeze thaw requires the sun to dry the ground and create cracks in the ground, when it rains and then freezes, the cracks face too much pressure from expansion as water freezes, so it blasts rock off to release the pressure. The key bit here is that it requires heat from the sun and rain; which Antarctica doesn't really have. What happens instead is ice-calving. This link should give some helpful information to your query. http://en.wikipedia.org/wiki/Ice_calving

Vein minerals can contain deposits of metals and other minerals, and occur in fissures or cracks of rock.

It cracks the rock
All rocks have cracks in them. If water fills the cracks and freezes, it expands and pushes the rock apart.
The rock cracks and weathers.
The ice expands in the crack and may split the rock, as will eventually the roots of a plant.
This can sometimes happen when water finds a way into cracks, which then freezes, expands, and this process repeats, making cracks.
As the water freezes in the cracks of rocks,the cracks expand. The process repeats itself and the rock eventually breaks.
The water expands as it is frozen and so the cracks are made wider/bigger :)
The ice expands as it freezes - which creates weak points in the rock, causing it to break apart.
Water expands when it freezes. In winter, water gets into minute cracks in the rocks and then as it freezes it expands and makes the cracks bigger. So more water gets in then freezes so the cracks get bigger still until the rocks break apart.
When ice forms in cracks in rocks, the kind of weathering is known as mechanical weathering. The type of mechanical weathering that freezes and thaws is frost wedging.
