Answer:
Stalactites and stalagmites are both mineral deposits that are commonly found in the caves. The stalactites are formed when the minerals fall down from the roof of the caves and are sharp, pointed downward. On the other hand, the stalagmites are formed from the subsequent deposition of the minerals on the floor that falls from the roof.
These are both formed simultaneously from the dropping of water containing calcium carbonates and carbon dioxide.
Sometimes, the stalactites and stalagmites are joined in certain places, and then they are called columns.
