The trace chemicals in rainwater erode the limestone - thus the cracks get wider.
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
limestone is a permeable rock that allows water to flow through its cracks and pores. As water moves through limestone, it can dissolve the rock, creating caves, sinkholes, and underground rivers. This process is known as karstification.
Clints are the raised blocks or sections of limestone pavement that are surrounded by grykes, which are the deep fissures or cracks in the pavement. They are formed by the natural processes of weathering and erosion over time, creating a characteristic pattern of blocks and gaps in limestone landscapes.
Here are some examples: 1. Water flowing over it, like the Grand Canyon. 2. Mechanical wearing, like from being walked on, ever seen steps with imprints? 3. Ice damage, water seeps into cracks and when cooled forms ice which expands and cracks the stone, like potholes forming.
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.

When water runs through cracks in limestone, it can create underground caves and caverns through a process called dissolution. Over time, the water dissolves the limestone and may form stunning structures like stalactites and stalagmites inside the caves.
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.

Sinkholes form when limestone dissolves and pores and cracks grow bigger.
Clints are formed through the weathering of limestone in karst landscapes. The process begins with the dissolution of the limestone by slightly acidic rainwater, which creates vertical joints or cracks. Over time, the erosion of these cracks widens them, resulting in flat-topped blocks of limestone known as clints, which are separated by deeper grooves called grikes. This characteristic landscape is typically found in regions with significant limestone deposits.
A hybrid bike with wider tires and a sturdy frame is the best choice for riding on crushed limestone trails.
Limestone pavements are formed through a combination of chemical weathering and erosion processes. Rainwater, which is slightly acidic, dissolves the calcium carbonate in the limestone, creating cracks and crevices. Over time, these cracks are widened by the freeze-thaw action of water, making the distinctive flat slabs of limestone pavement we see today.
Cold weather can cause limestone to deteriorate through a process called freeze-thaw weathering. When water seeps into cracks in the limestone and freezes, it expands, putting pressure on the rock and causing it to crack. Over time, this can lead to the breakdown of the limestone structure.
Limestone typically turns into marble when subjected to heat and pressure. Marble is a metamorphic rock with a finer texture and often exhibits a wider range of colors than limestone.
