Usually ice ! When water freezes to ice it expands slightly - It's strong enough to force rocks to split.
Frost wedging weathers rocks because water expands when it freezes, causing cracks to widen and break apart the rock over time. As water seeps into cracks in the rock and freezes, the growing ice crystals create stress and pressure that eventually breaks the rock apart.
The weathering process is known as frost wedging. Water seeps into cracks in rocks, freezes, expands, and exerts pressure on the rock, causing it to crack and break apart over time.
lava moving in between the cracks of the earths surface and pushing rocks together and apart.
Workers who seal cracks in the rocks at Mount Rushmore protect it from physical weathering caused by water infiltration and freezing and thawing cycles. By sealing the cracks, they prevent water from seeping into the rocks, which can weaken and cause them to break apart over time.
This process is called freeze-thaw weathering. It occurs when water enters cracks in rocks, freezes, and expands, causing the rock to crack and break apart as the ice melts and shrinks.
All rocks have cracks in them. If water fills the cracks and freezes, it expands and pushes the rock apart.
natural decomposition
Water can do this if it freezes
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.
The rocks cracks on everything
Rocks can be weathered by the wind or rain, or if water gets in some of the cracks, it would break apart
This process is called frost wedging or freeze-thaw weathering. Water enters cracks in rocks, freezes and expands, causing the rock to break apart over time.

Ice wedging is a form of mechanical weathering.
Root wedging is a process by which plant roots grow into cracks in rocks, causing the cracks to expand over time as the roots grow thicker. This process can contribute to physical weathering of rocks by breaking them apart.
use gun powder or plasic explosive in the middle
When magma pushes into vertical cracks and cuts through layers across, igneous rocks called dikes are formed. Dikes are one form of plutons. An intrusive dike would form.
