What is a speleothem?
A type of cave
What is the icicle like speleothem that grows down from the roof of a cavern?
stalactite
What is the is the icicle-like speleothem that grows down from the roof of a cavern?
stalactite
Use word in a sentence stalactite and stalagmite?
The cavern was filled with stalactites & stalagmites.From Wikipedia:"A stalagmite 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. This stalagmite formation occurs only under certain pH conditions within the underground cavern. The corresponding formation on the ceiling of a cave is known as a stalactite. If these formations grow together, the result is known as a column."
How are cave formations formed?
usually the rock is limestone, and some chemicals in nature react with it.It could also be prolonged exposure to water waves, or other deformations.+++To clarify the first sentence, the accepted meaning of the term cave formation as a noun, when referring to caves in limestone as the vast majority are, is "speleothem": stalactites, stalagmites and similar. These are deposits of calcite precipitated from solution in ground-water.Mechanical weatheringby water can produce wonderful shapes but in limestone it is still an adjunct to the primary process ofdissolution.
How are helictites different from regular stalactites?
A helictite is a speleothem found in lime stone caves that changes its axis from the vertical at one or more stages during its growth. They have a curving or angular form that looks as if they were grown in zero gravity. They are most likely the result ofcapillary forces acting on tiny water droplets, a force often strong enough at this scale to defy gravity.A Stalactite is cylindrical or conical mineral deposit projecting downward from the roof of a cave or cavern, formed by the dripping of water saturated with minerals. As this is formed with support of gravity, it grows vertically downwards. Stalactites form gradually as the minerals precipitate out of the saturated water. They usually consist of calcite but can also consist of other minerals.
What is the cone-shaped deposit rising from a cave called?
It is called Stalagmite. Stalagmite 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. This stalagmite formation occurs only under certain pH conditions within the underground cavern.[1] The corresponding formation on the ceiling of a cave is known as a stalactite. If these formations grow together, the result is known as a column. The Hall of Giants in the Carlsbad Caverns Stalagmites should normally not be touched, since the rock buildup is formed by minerals precipitating out of the water solution onto the old surface; skin oils can alter the surface where the mineral water will cling, thus affecting the growth of the formation. Oils and dirt from human contact can also stain the formation and change its color permanently.
Caverns form when rocks such as limestone are dissolved by a mixture of water and?
Limestone is made mostly of calcium carbonate and calcium sulfate. Limestone is eroded by water as the calcium carbonate and calcium sulfate of the stone disolves into running water. Also a factor: other things dissolved in the water. Carbon Dioxide disassociates in water becoming carbonic acid. This means that the more Carbon Dioxide in the water, the more acidic it is. The more acidic the water, the faster erosion can occur. When acidic ground water packed with lots of carbon dioxide is saturated with minerals - dissolved limestone - and that water enters an air filled chamber, the amount of mineral it can hold can suddenly change. This causes excess mineral to come out of solution as the water drips off the ceiling and onto the floor below into structures called Speleothem. .Think rock Icicle.

What's a stalactite?
when you go into a cave and you see large spikes pointing downwards from the ceiling then you are looking at a stalactite, spikes that point up are stalagmites. Stalactites hang from the ceilings like tights from a washing line, and stalagmites just MIGHT reach the ceiling! They hang from the top of a cave downwards, not from the bottom upwards, that would be a stalagmite. Just to help remember the difference, think "s-t-a-l-a-C (celing)-t-i-t-e" and "s-t-a-l-a-G (ground)-m-i-t-e." StalaCtite comes down from the celing. StalaGmite grows up from the ground. :) When I was a teenager at school the difference was explained to us as being; "Tights come down, and the Mites go up!" A stalactite (Greek stalaktites, (Σταλακτίτης), from the word for "drip" and meaning "that which drips") is a type of speleothem (secondary mineral) that hangs from the ceiling or wall of limestone caves. It is sometimes referred to as dripstone.
In what ways have caves provided important clues about the past?
Caves have preserved ancient artifacts, fossils, and rock art which provide valuable insights into past cultures, environments, and climates. Additionally, stalactites and stalagmites in caves can be used to track changes in climate and geology over long periods of time. Studying cave formations and sediments can also help scientists understand past geological events such as earthquakes and shifts in sea levels.
