Groundwater can dissolve rock, typically limestone or dolomite, over time as it flows through cracks and fractures underground. This process forms caves through a combination of chemical weathering and erosion, creating underground voids and passages that we see as caves.
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.
Groundwater erosion can dissolve the underlying rock or soil beneath the surface over time, creating voids or cavities. If these voids grow large enough to weaken the surface layer, it can collapse suddenly, leading to the formation of a sinkhole. This process is accelerated in areas with soluble rock such as limestone or gypsum.
Groundwater creates caves through a process called chemical weathering, which dissolves rock over time. As water seeps through the ground, it reacts with minerals in the rock, slowly eroding it and creating cavities. Over thousands of years, these cavities can grow larger and eventually form caves.
acidic groundwater
This would usually be caused by the dissolution of soluble rocks such as limestones. Dissolution is a chemical weathering process.
Groundwater seeping through the limestone rock over thousands of years dissolved the rock, creating cracks and fissures. Eventually, these cracks formed larger passageways that became the cave system of Lascaux.
Groundwater affects cave formation by dissolving minerals in the rock, creating passageways and chambers. Over time, this process can lead to the formation of stalactites, stalagmites, and other cave formations. Additionally, groundwater can contribute to the erosion of cave walls and ceilings, shaping the overall structure of the cave.
Black Chasm Cavern was formed by a process called sulfuric acid dissolution, where acidic groundwater slowly dissolved away the limestone rock to create the cave's intricate formations. Over time, mineral-rich groundwater filled the cave passages, leaving behind beautiful stalactites and stalagmites.

acidic groundwater
A cave is a void (hole) in the ground. An aquifer is a region of water-permeable rock that holds groundwater; it may (or may not) contain caves.
Meramec Caverns in Missouri formed over millions of years through the erosive action of groundwater dissolving the limestone bedrock to create the cave system. The slow process of acidic water dissolving the soluble rock formed the caverns, stalactites, and stalagmites that visitors see today.
