More often stalactites than stalagmites, but they can sometimes be found under arches such as railway bridges built of limestone masonry and/or lime mortar, and exposed to the weather.
In caves formed in limestone - as are most of the world's caves although not all such caves contain stalagmites and stalactites. They are precipitations of calcite dissolved from the host limestone by carbonic acid - rain water acidified by atmospheric carbon dioxide dissolved in it.
They typically form in caves where they can grow undisturbed for hundreds of years. Stalagmites grow from the floor up and stalactites stick to the ceiling. Dripping water deposits minute amounts of limestone that build up over the years. +++ You do sometimes find small, rather coarse versions growing under bridges etc.built from bricks or ashlar masonry and mortar. Here, the calcite that is their constituent mineral has been leached from the structure's mortar. However caves in limestone (the rock hosting by far the majority of caves) are the natural home for stalagmites and stalactites, and their related formations.
condensation from the ceiling drops water onto the ground and over the years it drops more and more water and the water dries and the minerals in it build up until it rises out of the ground .... stalagmites are rare as they come from the ground ... normally you find stalactites
It's called a column, there's no more technical term than that, as far as I can find. +++ You are right; "column" is both common and technical term for it.
They can topple, but not usually, because stalagmites grow up from the, or a, floor. If the floor moves - perhaps because it was a boulder or a mud-bank rather than bed-rock, and it slumps - then so will the stalagmite. . I wonder if you meant stalactites. They can drop from the ceiling by their own weight, but that's very rare. Some of the fallen stalactites you find may have been dislodged by a minor earthquake at some time in the cave's geological history; or more recently by basting shock if the host hillside is being quarried. Others, in active stream caves, have been broken off by very rare, extreme, floods.
in caves
Precipitated as stalactites, stalagmites etc - and it is the primary constituent of the limestone in which the vast majority of caves form!

Caves formed in limestone, as the vast majority are - but there are many caves that contain few or no "speleothems" as the formations are know collectively. The distribution and scale of the formations is subject to many, complex factors.
Stalactites are often found in caves.

I assume you mean caves well decorated with stalagmites etc. They are in most limestone caving areas but if you want to visit them either take up caving properly - for both your safety and to learn to protect the caves you visit - or visit show-caves.

Hi First you go on the right side of the falls and find the biggest biggest bush and go into the caves climb on the Stalagmites ( Big pointy thingies) and go on the other side! There you will find the purple diamond!
