Running water, and the acids from dissolved gases, slowly carve out the stone to form an erosive cave. Where limestone is present above the cave, it will drip out as calcium bicarbonate in water, which reverts to particles of calcium carbonate in air. If the water carries to the floor of the cave, stalagmites (limestone pinnacles) are formed. If the calcium precipitates before it can drip, an "icicle" of limestone, a stalactite, hangs from the ceiling. Usually these forms are created simultaneously, and may merge to form columns or sheets of columns.
Unlike their icy counterparts, stalactites and stalagmites take hundreds to thousands of years to form, at an average of 5/1000ths of an inch (.13 mm) a year. A stalagmite in an Oregon cave has grown less than 1/4 of an inch since it was broken off 100 years ago!

Stalac"tites", top, or on the roof of the cave. Stalagmites form on the floor of caves.
Stalactites and stalagmites are corresponding rock formations , stalactites being the ones on the roof of the cave and stalagmites the ones on the cave floor. Why are they formed? They are formed because water leaking into the caves craves out the rocks slowly into stalagmites and stalactites.
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.
Stalagtites are structures that hang down like icicle s from the cave ceiling; Stalagmites are what comes up from the cave floor.
Stalactites and stalagmites are found in limestone caves. Stalactites hang from the ceiling, and stalagmites come up from the ground.

Stalactites and stalagmites can be found in various caves throughout the UK, such as Cheddar Gorge in Somerset, Wookey Hole Caves in Somerset, and Dan yr Ogof in Wales. These formations are created over thousands of years by mineral-rich water dripping from the cave ceiling and depositing calcium carbonate.
Kuwait doesn't have caves as big to have stalactites and stalagmite
Lime stone caves!

Stalactites and stalagmites are precipitated calcite.
Which ones? Oh, and "stalactites". They form in caves developed in limestone.
