not 100% sure but I think it's that the rocks expand when they get hotter and then as the contract when they cool down cracks appear
weathering and plant growth growing through and eventually causing a crack in the rock
Weathering, specifically freeze-thaw weathering. If rain gets into the crack and freezes, it expands and pushes the crack wider.
Ice expanding in the crack as it freezes can exert pressure and force the crack to widen, eventually causing the rock to split. This process, known as freeze-thaw weathering, is a common geological phenomenon that occurs in areas with fluctuating temperatures.
Thermal expansion causes repeated expansion and contraction within the rock. This repeated stress breaks bonds and eventually causes the rock to crack. Thermal expansion is classified as a type of physical or mechanical weathering.
Yes, forest fires can speed up the weathering process. The intense heat from the fires can break down rock and soil, increasing the surface area exposed to weathering agents like water and air. Additionally, the removal of vegetation due to fires can lead to increased erosion and soil degradation, further accelerating the weathering of underlying materials. This combination of factors can enhance both physical and chemical weathering in affected areas.
Sun or forest fires can cause rocks to crack through a process called thermal stress. When rocks are heated rapidly by intense sunlight or fires, they can expand unevenly, leading to cracks forming due to the differential expansion and contraction of the rock material. Over time, this repeated stress from heating and cooling can cause the rock to fracture or break apart.

The agent in mechanical weathering where the sun or forest fire causes rocks to crack is thermal expansion and contraction. This process occurs when rocks are exposed to heat from the sun or a fire, causing them to expand and contract at different rates, leading to cracks and eventual breakdown.
Weathering, specifically freeze-thaw weathering. If rain gets into the crack and freezes, it expands and pushes the crack wider.
Weathering processes, such as freezing and thawing, and chemical weathering from exposure to water and acids are the most likely causes for rock to crack and crumble. Over time, the expansion and contraction of these forces weaken the rock structure, leading to eventual breakage.

If there is movement of rock along this crack, then it is called a fault.
A crack rock can be almost any size. Usually about half an inch in diameter.
Ice freezing in a crack of a rock is considered weathering.
