A vertical gap in limestone is called a grike. The remaining blocks of rock are called klints. The cracks in limestone are called joints.
Regions of the Earth's surface with abundant limestone exposed are typically known as limestone terrains or limestone landscapes. These regions often feature distinctive topography due to the erosion of the soluble limestone rock by water, forming features such as caves, sinkholes, and limestone pavements.
A vertical section through all of the soil horizons is called a soil profile.
Hollow spheres in limestone rock are called vugs. Vugs are formed when a cavity in the rock is later filled with minerals or crystals. They can vary in size and shape and are often sought after by collectors for their unique beauty.
Clay can turn into limestone through a process called diagenesis, where the clay particles are subjected to compaction and cementation, forming a new rock material. Over time, the minerals in the clay are altered and precipitate out to form calcium carbonate, which is the primary mineral in limestone.
When rain falls on limestone, a chemical reaction occurs causing the limestone to dissolve. This process is called carbonation and results in the formation of calcium bicarbonate, which can be washed away over time by the rainwater. As a result, limestone can be weathered and eroded by rainfall.
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 called limestone because it has lime in it from the sea water it if formed in.
Recrystallized limestone is generally called marble. Recrystallized quartz sandstone is generally called quartzite. There is no such thing as quartz limestone.
If it is a horizontal crankshaft the gap is .030 if it is a vertical crankshaft it is .020

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.
Vertical grooves are called "striations."
Vertical poems are called acrostic poetry.
A vertical row of bricks is called a channel.
The gap for the plug on all horizontal shafts is .030" and some vertical shafts are .020"
They are simply just called lines.
