Limestone
somewhere in earth
A stalagtite is a mineral formation that forms at the top of a limestone cave. A stalagmite is a mineral formation that rises from the bottom of a limestone cave.
The ground-water is a solution of calcium carbonate it has dissolved from the limestone above the cave. The mineral is subsequently precipitated as deposits of calcite in the cave: stalatcties & stalagmites, and flowstone on the floor and walls.
I'm not really sure what you had in mind. Given that the cave is in limestone (as the vast majority of them are) there has to be a dimensional limit to the dissolution and erosion processes. The floor is there by default: it is the lowest surface along a passage at that given time in the cave's development.
Most sinkholes form when mildly acidic water dissolves limestone underground, this forms a limestone cave. A sinkhole occurs when the cave collapses.

A cave?
Yes, caves are formed when carbonic acid, which is created by the reaction of water with carbon dioxide, dissolves underground limestone. Over time, the dissolved limestone is carried away by water, creating large openings and chambers that we call caves.
Caves are typically formed from a combination of natural processes such as erosion by water, chemical weathering, and the dissolving of rock formations like limestone and dolomite. Over time, these processes create underground cavities and passages that can develop into complex cave systems.
Mammoth cave began forming about 10 million years ago when an ancient sea covering the central United States disappeared and erosional forces let cracks and holes expose the limestone that was beneath the sea. Rainwater began to get underground and hallowed out the cave.
Limestone and limestone formations.
It causes dissolution which initially creates vesicles within the limestone and may ultimately result in the formation of cave systems.
Many caves are found in limestone rock because limestone is a sedimentary rock that is easily eroded by water. Over time, the water dissolves the limestone, creating underground passageways and caverns. Additionally, limestone is often found in areas with abundant rainfall, which further contributes to the formation of caves through the process of water erosion.

Most stalactites are limestone. Water, often rainwater, seeps through material which causes it to absorb carbon dioxide, as it seeps further it dissolves limestone. Then when it reaches the ceiling of a cave it slowly begins to forms droplets. As these dry they deposit the limestone on the ceiling. This happens again and again, one drop at a time, and very slowly over years this deposit grows forming a stalactite.
Mother Shipton's Cave in England is a natural limestone cave formed over thousands of years through the geological process of erosion. The cave contains unique rock formations and underground water streams that contribute to its eerie and mysterious appearance.
