Stalactites are found in limestone caves. They occur as a pair with a stalagmite. As water that contains acid drips from the roof of the cave if dissolves some of the limestone and drips to the floor. As the water drips, the stalactite is formed from the roof of the cave and the corresponding stalagmite form below as the water drips onto the floor.
Stalactites are formations hanging from cave ceilings, created from calcium carbonate as slightly acidic water drips and leaves deposits. This process involves the dissolution of limestone and occurs over many years. They often appear alongside stalagmites that form from the water droplets on the cave floor.
