The trace chemicals in rainwater erode the limestone - thus the cracks get wider.

What are horizontal cracks in limestone called?
Limestone is formed in layers called Bedding Planes and the vertical cracks are called Joints. The horizontal cracks are not given a specific name - however I am sure someone will want to contradict this
Water often passes through beds of limestone because?
the beds have cracks and fissures in them
Why would it be more likely to find a cave with limestone bedrock than granite?
Limestone forms in such a way that there are often blocks, as there are cracks perpendicular to the strata. These cracks allow water to actually flow. When the water flows, it dissolves calcite from the limestone, making the crack more pronounced. Water can flow vertically and horizontally in this way. This, after many years, erodes large caverns in the rock.
How does water in the spaces of a limestone cause physical weathering of the limestone?
Water in the spaces of limestone can cause physical weathering through a process called freeze-thaw. When water seeps into the cracks and pores of the limestone, it freezes and expands upon freezing, exerting pressure on the surrounding rock. This expansion and contraction cycle weakens the limestone, causing it to crack and break apart over time.
What causes cracks in a rock to get bigger?
Weathering, specifically freeze-thaw weathering. If rain gets into the crack and freezes, it expands and pushes the crack wider.
What is formed when water runs through cracks in limestone?
Larger cracks, usually. From chemical weathering of the limestone by slightly acidic rainfall.
Water freezes in the cracks in rocks. plants grow into the cracks in rocks?
cracks open wider
Water freezes in the cracks of rocks and plants grow into the cracks of rocks what happens?
cracks open wider

How does limestone erode?
Limestone erodes with water. Limestone can also erode through water getting in to the cracks and then freezing. This causes the crack to expand and will begin to erode the limestone.
What is the effect when water freezes in to cracks?
The water expands as it is frozen and so the cracks are made wider/bigger :)
What is a vertical gap in limestone called?
A vertical gap in limestone is called a grike. The remaining blocks of rock are called klints. The cracks in limestone are called joints.
What plant roots grow into cracks in rocks and force the cracks wider?
I'm not for sure but I think its weeds
How does water entering spaces in limestone cause physical weathering?
Mainly through expansion of cracks and fissures from frost expansion which leads to further and deeper cracks and fissures. Plant roots seeking moisture may extend roots into limestone cracks and fissures, prying the rock apart.
When do sinkholes form?
Sinkholes form when limestone dissolves and pores and cracks grow bigger.
Water often passes through beds of limestone because?
the beds have cracks and fissures in them
How does underground water cause chemical weathering of limestone?
Rainfall that seeps through cracks in the bedrock is slightly acidic. The acid reacts with the calcium carbonate in the limestone, causing dissolution of the rock.
