Water seeps through the roof of a cave in a limestone region forming calcium bicarbonate

The solution drops slowly form the roof to the floor of the cave

The solution evaporates and leaves behind crystals of calcium carbonate

More deposits of crystals pile on top of the first one and grow upwards towards the roof.

Formation of stalagmite
- Rainwater dissolves carbon dioxide as it passes through the car to form weak carbonic acid.
- The rainwater dissolves calcium carbonate as it percolates through limestone joints
- The solution in form of calcium hydrogen carbonate drips to the floor of the cave.
- Some of the water and carbon dioxide are released leaning behind deposits of calcium carbonate.
- The calcium carbonate deposits grow upwards from the floor of the caves to form finger like projections called stalagmite.
