Step 1
Formation of a Stalactite
Answer
A stalactite forms through the process of mineral deposition in caves. Water, which contains dissolved calcium carbonate from limestone, drips from the cave ceiling. As the water evaporates, it leaves behind mineral deposits, gradually forming icicle-shaped structures hanging from the roof. This process takes a considerable amount of time, often thousands of years.
Diagram: Include a diagram showing the water dripping from the ceiling and the stalactite formation over time.
Named Example: The Stalactites in the Ailwee Cave are a notable example of such formations.
Step 2
Formation of a Stalagmite
Answer
A stalagmite is formed on the cave floor beneath a stalactite through the accumulation of mineral deposits. When water drips from a stalactite, it continues to carry minerals. When it reaches the cave floor, some of these minerals are left behind as the water evaporates.
Diagram: Include a diagram illustrating the water dripping from the stalactite onto the cave floor, forming the stalagmite over time.
Named Example: An example of stalagmites can be seen in the Doolin Cave, which showcases impressive growth.
