Hit it with another rock, hammer, or something else hard.
Heat and/or cool the rock
Certain plants are able to get their roots into cracks in rocks. As the plant grows, the thickening roots may force the crack to widen. That, and the expanding ice in winter, may crack the rock wide open.
Ice freezing in a crack of a rock is considered weathering.
The crack would expand because the water in the rock, as it freezes, expands.

The crack get bigger and bigger
When you crack open a rock, you may find mineral crystals, fossil imprints, or veins of minerals such as quartz or calcite. The middle of a rock can reveal its composition, history, and formation process.

If there is movement of rock along this crack, then it is called a fault.
The water can fill the crack and exert pressure on the surrounding rock walls, potentially widening the crack over time through hydraulic action and freeze-thaw cycles. This process is known as hydraulic fracturing or water-induced fracturing.
When water seeps into a crack in a rock during warm weather and then freezed in cold weather , it expands. And when it expands, it pushes against the sides of the crack forcing it to open wider.
A crack rock can be almost any size. Usually about half an inch in diameter.

a spring whose water flows from a crack in the cap rock over the aquifer
A joint is a crack in rock; a fault is a crack in rock along which the rocks have been displaced.
