What is a cave column called?
A prominent cave column in the Caverns of Sonora. Cave columns occur when stalactites and stalagmites fuse together. This column then grew a series of cave formations, or speleothems, known as “cave popcorn.”
What is a caves ceiling called?
The decorative dripstone features are called speleothems (from the Greek spelaion for cave and theme for deposit). The most familiar speleothems are stalactites and stalagmites. stalactites hang downward from the ceiling and are formed as drop after drop of water slowly trickles through cracks in the cave roof.
Why do caves have stalagmites?
The mineral calcite is dissolved from the limestone rock in which a cave is formed. If the water that drops to the floor of the cave still has some dissolved calcite in it, it can deposit more dissolved calcite there, forming a stalagmite.
What are mineral formations called?
Speleothems
Speleothems are mineral formations occurring in limestone caves, most commonly as stalagmites and stalactites or slablike deposits known as flowstones.
What does the term Speleothem mean?
cave deposit
Definition of speleothem : a cave deposit or formation.

What kind of structures are found in caves?
Columns form where stalactites and stalagmites join. Sheets of calcite growths on cave walls and floor are called flowstones. Other stalactites take the form of draperies and soda straws. Twisty shapes called helictites warp in all directions from the ceiling, walls, and floor.
How are stalagmites and flowstones formed in a cave?
The icicle-shaped formations are called stalactites and form as water drips from the cave roof. Stalagmites grow up from the floor, usually from the water that drips off the end of stalactites. Columns form where stalactites and stalagmites join. Sheets of calcite growths on cave walls and floor are called flowstones.
How does a speleothem form in a cave?
Speleothems form as the carbon dioxide in the acidic water escapes in the airiness of the cave and the dissolved calcite hardens once again. The icicle-shaped formations are called stalactites and form as water drips from the cave roof.
What causes a cave to become a cave?
The passages widen as more water seeps down, allowing even more water to flow through them. Eventually, some of the passages become large enough to earn the distinction of “cave”.
