Ice naturally makes cracks when it is frozen. Not large cracks, but cracks. Water seeps in through these cracks and freezes them. The crack expands due to the frozen water, or new ice. The cycle continues over and over again until the piece of ice finally breaks.
Ice wedging can break apart rocks when water seeps in cracks of roads or rocks and continues freezes and thaws until the rock eventually creates a pot hole

Ice or frost wedging
The roots of certain plants can break or crack into a rock, making the rock more susceptible to frost wedging (ice wedging).
wedges of ice widen and deepen cracks in a rock, and can even break the rock into two at some point.
Ice wedging breaks the rock apart. Water goes into cracks in the rock and when it freezes, it expands. This can cause rocks to split and eventually break. (see the related link)
Ice wedging has 3 forms and they are Active, Inactive and Ice wedge Casts.
Ice wedging is a type of mechanical weathering.
wedges of ice widen and deepen cracks in a rock, and can even break the rock into two at some point.
frost wedging is when water gets into a crack in a large rock and when ice freezes it expands and when it expands inside a rock it might break in half
When water freezes, it expands. This can cause rocks to crack or break, then the water thaws to create a visible gap in the rock. This is ice wedging.
The general term for this is "erosion".
