It has a crack so it erodes the insides.
On contact with water lava will cool rapidly to form rock.
When water enters a crack in a rock and freezes, it expands as it turns into ice. The force of the ice expanding can exert stress on the surrounding rock, causing the crack to widen or the rock to break apart. Over time, repeated cycles of freezing and thawing can lead to the disintegration of the rock.
Some of the most important rock types in geology are Igneous Rock & Metamorphic Rock.

Question is not stated properly. What it seems to be asking is the relationship between rocks and Geology. Rocks are basically what the Earth is made of...you have tiny tiny rocks....great big giant rocks....melted rock. Everything that is not water or air is rock and is therefore a part of the study of the Earth...that we call Geology.
Ice Wedging Or Frost Wedging
Aquifers are replenished through a process called recharge, where water from precipitation, rivers, or lakes infiltrates the ground and enters the underground reservoir. This water slowly percolates through the soil and rock layers to refill the aquifer. The rate of recharge depends on factors such as land use, climate, and geology.

Karst Geology, Is water altering rock at high tempreatures @ (100-300 deg C) water is impotant in changing the rock at much low temps of (25deg c or less) The interaction of Dolomite, calcite and limestone.
the ice expands the rock
Cryoseisms are caused by cracking actions in frozen rock or soil. Water enters the rock, freezes and expands The expansion builds up until the rock cracks
The crack would expand because the water in the rock, as it freezes, expands.
