A stalactite drips water onto the floor of a limestone cave and a small source or mineral is carried with each drop. Over time as the water runs off or evaporates, the buildup of this mineral will create a stalagmite. They may take thousands of years to grow a few inches. When a stalagmite and a stalactite meet, they form a column.
Stalagmites rise from the floor of a limestone cave due to the dripping of mineralized solutions and the deposition of calcium carbonate.
The primary mineral of both stalactites and stalagmites is Calcite, the crystalline form of Calcium Carbonate that is the main ingredient of limestone. Their mode of formation is the same, precipitation of calcite; the different names reflect only their different positions. The other mineral solutions implied above, are trace metallic compounds that give the formations their colour.
No, it is stalactites that form on the ceilings. Stalagmites form on the cavern floors.
Stalagmites
Stalactites and stalagmites join to form columns. These columns are created when a stalactite hanging from the ceiling of a cave and a stalagmite growing from the floor eventually meet and fuse together.
Yes, stalagmites are typically made of limestone. They form from mineral deposits left behind by dripping water in caves, which contain calcium carbonate. Over time, these deposits accumulate to form the stalagmites.
Stalactites hang tightly to the ceiling of a cave, while stalagmites might grow to reach the cave floor. The names reflect their formation as water drips from the ceiling to form stalactites, and drips onto the cave floor to form stalagmites.
No, it is stalactites that form on the ceilings. Stalagmites form on the cavern floors.
Calcium Carbonate
No, they form on the ground. Stalactites form on the ceiling.

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.)

They are stalagmites.
A pillar a column or sometimes a stalagnate.
Which ones? Oh, and "stalactites". They form in caves developed in limestone.
Within caves in carbonate rocks.
