When water freezes in cracks in rock does it expand and make the cracks bigger?

Yes. The expanding force of freezing water has been known/used to actually split stone.
add This technique was used to break crystalline stone from at least Roman times. A series of holes, each about the size and length of your index finger, are drilled in the rock and filled with water. Left to freeze overnight, the expansion of water on freezing will crack the rock along the line of holes.
A similar technique was used to split slabs of stone, and the Dunedin Railway Station is constructed of basalt rock split by this method. In this local case, the holes were plugged with a hardwood peg, driven in, wetted, and covered with a sack overnight. The expansion of the hardwood accomplished the rock splitting.

How do rocks change when water in them freezes?
As the water freezes in the cracks of rocks,the cracks expand. The process repeats itself and the rock eventually breaks.
How does water work to cause mechanical weathering called frost wedging?
water finds its way into small cracks and when it freezes it expands making the crack bigger
How does melting water weather a rock?
the water freezes and then cracks the rock
Why does frozen water mack larger cracks in rocks?
Because when water seeps into cracks and freezes, the material gets pushed outwards, because water exapands as it freezes. This process is called ice wedging.
What type of weathering occurs more rapidly in climates that experience frequent freezes and thaws?
It is called "frost weathering" or "freeze-thaw weathering" and occurs because water that freezes within the cracks in rocks will expand, compressing and eventually fracturing the rock.
Why do cracks in a rock get bigger if water freezes in them?
Frozen water molecules are larger and expand. In liquid form H2O is smaller
How do rocks change when water in them freezes?
As the water freezes in the cracks of rocks,the cracks expand. The process repeats itself and the rock eventually breaks.
How does water help break rocks 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.
What is the effect when water freezes in to cracks?
The water expands as it is frozen and so the cracks are made wider/bigger :)
Does water expand?
When it freezes.
How does freezing water cause rocks to weathering?
Water goes into small cracks in the rocks and then freezes. Water expands as it freezes and the expansion pushes outwards on the crack in the rock making it bigger. Eventually this process causes the rock to crack and flake apart
What is the effect of water freezes in the cracks in rock?
The rock cracks and weathers.
What happens to the volume of a water balloon when it freezes?
As the water freezes, it will expand.
Water freezes in the cracks in rocks. plants grow into the cracks in rocks?
cracks open wider
How does water work to cause mechanical weathering called frost wedging?
water finds its way into small cracks and when it freezes it expands making the crack bigger
Does salt water expand when it freezes?
NO
How does water affect rock when it freezes inside the rock?
Since water expands when it freezes, it causes cracks in rocks when it freezes inside them.
