Stalagmites form from the mineral calcium carbonate depositing on the ground below a drip of calcium carbonate which is the stalactite. Over geologic time the mineral slowly continues to build layers upon layers in their natural environment, caves. However stalagmites can form below a roof made of concrete, especially in areas where the humidity is very high. For instance the bathrooms/showers of some apartment buildings are one on top of the other, if the ceiling/floor between each level leaks it can produce a stalactite on the ceiling and a stalagmite on the floor of every level with the exception of the top floor because there is no bathroom above it, unless the building has a massive leakage problem.
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
When stalactites and stalagmites join it is called a column
Stalac"tites", top, or on the roof of the cave. Stalagmites form on the floor of caves.

No, they form on the ground. Stalactites form on the ceiling.
Stalagmites
They are stalagmites.
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.)
Which ones? Oh, and "stalactites". They form in caves developed in limestone.
No, on the floor (G for ground). Stalactites are the ones on the roof!
