This is caused by the concentration of minerals solidifying over time, normally from groundwater trickling through cracks in the roofs of such caverns contains dissolved calcium bicarbonate. When a drop of water comes in contact with the air of the cavern, some of the calcium bicarbonate is transformed into calcium carbonate, which is precipitated out of the water solution and forms a ring of calcite on the roof of the cavern.
When stalactites and stalagmites join it is called a column
rain
No, it is stalactites that form on the ceilings. Stalagmites form on the cavern floors.
Stalagmites form when water from the stalactite drips down water and that water has minerals in it
No, on the floor (G for ground). Stalactites are the ones on the roof!
i don't awnser this question experts do like you who want to now this question
Stalactites are a result of the processes of chemical weathering, not a form of chemical weathering.

Same way as any stalactites in any karst caves form: precipitation of calcium carbonate from solution in ground-water.
No, they form on the ground. Stalactites form on the ceiling.
Do you mean "How are stalactites formed?" ? They are deposits of calcite precipitated from solution in water dripping from joints in cave roofs.
The opposite would be stalactites, which form from the ceiling down, while stalagmites form from the floor up. (The venerable mnemonic is that stalactites hold tite/tight to the ceiling.)
Sediments in sedimentary rocks are often caused by precipitation.
No, it is stalactites that form on the ceilings. Stalagmites form on the cavern floors.
