it gets larger because it absorves water

∙ 12y ago
When water freezes, it expands and exerts pressure on the rock walls, causing the cracks to widen. Over time, repeated freeze-thaw cycles can further widen the cracks as the ice continues to expand and contract. This process eventually weakens the rock structure, leading to larger cracks.

Why does frozen water mack larger cracks in rocks?
When water freezes, it expands in volume, exerting pressure on the surrounding rock. This increase in pressure causes the rock to crack and eventually break apart. The repeated cycles of freezing and thawing can exacerbate this process, leading to larger cracks in the rock over time.
What type of weathering involves water filling cracks in a rock?
The type of weathering that involves water filling cracks in a rock is called frost wedging. When water enters the cracks in a rock and freezes, it expands, causing the crack to widen and eventually break apart the rock.
Which type of weathering involved water filling cracks in a rock?
Frost Weathering!
How does freezing water affect the weathering of rocks on a mountain's pinnacle?
Freezing water can cause water to seep into cracks in the rock on a mountain's pinnacle. When the water freezes, it expands, exerting pressure on the rock and potentially causing it to fracture. This repeated freeze-thaw cycle can contribute to the weathering and erosion of the rocks over time.
How water could cause cracks to form in gritstone cliffs?
Water can penetrate the small pores in gritstone cliffs. When the temperature drops, the water freezes and expands, putting pressure on the rock and causing cracks to form. Over time, repeated cycles of freezing and thawing can widen these cracks, eventually leading to the formation of larger fissures and eventual crumbling of the rock.

What is cryoseism?
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
Why do cracks in a rock get bigger if water freezes in them?
When water freezes, it expands in volume, creating pressure within the crack. This pressure can widen the crack as it pushes against the rock walls. Over time, this repeated cycle of freezing and thawing can gradually widen the crack and cause it to grow larger.
What is the effect of water freezes in the cracks in rock?
The rock cracks and weathers.
What is the effect when water freezes in to cracks?
When water freezes in cracks, it expands as it turns into ice. This expansion puts pressure on the surrounding rock, causing the crack to widen and potentially leading to fracturing and breaking of the rock over time. This process is known as freeze-thaw weathering and can cause significant damage to rocks and structures.
Why does cement crack after salt is put on it when it is frozen?
When cement is frozen it shrinks. the salt adds heat and it expands. The cement is not used to the change and it expands to much and it cracks. just like when paper rips. =============================== I have a different mechanism to propose: -- Salt on the surface of the frozen rock melts the fine layer of ice on the rock, just as it does when salt is used on the roads or sidewalks. -- The liquid water seeps into microscopic cracks in the cement. -- When the water re-freezes, it expands, cracking the cement.

When water frezzes and cracks the rock this is an example of?
Erosion.
Why do cracks in a rock get larger because water has frozen in them?
When water freezes, it expands. This expansion exerts pressure on the walls of the crack, causing it to widen over time. As the process repeats, the crack becomes larger due to the repeated cycle of freezing and thawing.
