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
The trace chemicals in rainwater erode the limestone - thus the cracks get wider.
the beds have cracks and fissures in them
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.
Recrystallized limestone is generally called marble. Recrystallized quartz sandstone is generally called quartzite. There is no such thing as quartz limestone.
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.
A vertical gap in limestone is called a grike. The remaining blocks of rock are called klints. The cracks in limestone are called joints.
They are called bedding planes

Larger cracks, usually. From chemical weathering of the limestone by slightly acidic rainfall.
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.
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.
This is because in the wet climates the limestone will break apart due to the rain. And in dry climates it does nothing to the limestone. Therefore, this is why limestone can form cliffs in dry climates than wet climates.

Limestone is called limestone because it has lime in it from the sea water it if formed in.
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.
