Stalactite.
<u>Stalactite:</u>
- Often, stalagmites develop up from the cave floor, whereas stalagmites typically grow down from the cave roof.
- It's simple to distinguish between the two since stalagmites have a "G" for ground and stalactites have a "T" for top.
- Typically made of calcium carbonate, stalagmites can also be made of lava, mud, peat, pitch, sand, sinter, and amber.
- A single drop of water rich in minerals is the origin of all limestone stalactites.
- The smallest ring of calcite is left behind by the falling water drop.
- Another calcite ring is left behind with each new drop of water that develops and drops.
