A stalagmite (from the Greek stalagma ("Σταλαγμίτης"), "drop" or "drip") is a type of speleothem that rises from the floor of a limestone cave due to the dripping of mineralized solutions and the deposition of calcium carbonate. A fungus (ˈfʌŋgəs is a eukaryotic Organism that is a member of the kingdom Fungi (ˈfʌndʒaɪ Carlsbad Caverns National Park is a United States National Park located in the Guadalupe Mountains in southeastern New Mexico. Greek (el ελληνική γλώσσα or simply el ελληνικά — "Hellenic" is an Indo-European language, spoken today by 15-22 million people mainly A speleothem (from the Greek for "cave deposit" commonly known as a cave formation, is a secondary mineral deposit formed in a Cave. A floor is the walking surface of a room or vehicle Floors vary from simple dirt in a cave to many-layered surfaces using modern technology Limestone is a Sedimentary rock composed largely of the Mineral Calcite ( Calcium carbonate: CaCO3 A cave is a natural underground void large enough for a human to enter In Chemistry, a solution is a Homogeneous Mixture composed of two or more substances Calcium carbonate is a Chemical compound with the Chemical formula Ca[[Carbon C]] O 3

The corresponding formation on the ceiling of a cave is known as a stalactite. A stalactite ( Greek stalaktites, (Σταλακτίτης from the word for "drip" and meaning "that which drips" is a type of Speleothem If these formations grow together, the result is known as a column.

When touring caves with stalactites and stalagmites you might be requested to not touch the rock formations. This is a List of rock formations meaning isolated scenic or spectacular surface rock outcrops This is generally because the formation is considered to still be growing and forming. Since the rock buildup is formed by minerals solidifying out of the water solution onto the old surface, skin oils can disturb where the mineral water will cling, thus affecting the growth of the formation. The skin is the outer covering of living tissue of an animal (or plant Oils and dirt from the hands can also stain the formation and change its colour permanently.

Stalagmites can also form in lava tubes, although the mechanism of formation is much different. Lava tubes are natural conduits through which Lava travels beneath the surface of a lava flow expelled by a Volcano during an eruption Stalactites and stalagmites can also form on concrete ceilings and floors, although they form much more rapidly there than in the natural cave environment. Concrete is a construction material composed of Cement (commonly Portland cement) as well as other cementitious materials such as Fly ash and Slag A cave is a natural underground void large enough for a human to enter
