During the Cretaceous period much of the interior of the United States was covered in a warm, shallow sea, which is conducive to the formation of limestone.

Groundwater is most effective in eroding soluble rocks like limestone, where it dissolves and carries away materials easily. Areas with high concentrations of limestone, such as karst landscapes, are particularly prone to groundwater erosion. Additionally, areas with abundant underground water flow or heavy precipitation can also experience significant erosion from groundwater.
Limestone is commonly found in nature in areas with ancient sea beds, such as marine environments and seabeds. It is formed from the accumulation of marine life remains like shells and coral that undergo compression over time. Limestone can also be found in caves and cliffs formed by the erosion of these marine deposits.
Yes, limestone from areas where shelled sea creatures are highly abundant typically contains more carbonate. Shelled sea creatures like mollusks and corals have shells made primarily of calcium carbonate. Over time, as their shells accumulate and get compacted, they form limestone. As a result, limestone from these areas will have a higher carbonate content compared to limestone from areas without such abundant sea creatures.
Limestone is the type of rock that is commonly found in areas with a lot of caves. Limestone is made of calcium carbonate, which is soluble in water. Over time, as rainwater seeps into the ground, it dissolves the limestone and creates openings and caves in the rock.
Limestone. However most large masses of limestone formed from coral reefs, not shells. The shell fossils in this limestone are "incidentals" due to shell dwelling organisms living on the periphery of the reef, not the bulk of the limestone.
Limestone is obtained through mining or quarrying. Large deposits of limestone can be found in many parts of the world and are typically extracted using heavy machinery and explosives. After extraction, the limestone is processed and crushed into various sizes for use in construction, agriculture, and other industries.
Because limestone uplands with appropriate internal geology and surface drainage in areas of long-term, suitable climatic conditions are so widespread. Not all limestone areas support caves though.
In some geographical areas, yes. In other areas, no. It depends on the geology of the area.
