Although both Stalagmites and stalactites are common cave formations, their creation is different. A stalagmite grows from the floor upward as drops of calcite-laden water fall from the ceiling, creating an ever-growing mound of calcite. A stalactite grows from the ceiling down as calcite-laden water seeps into a space and hangs on the ceiling. The water evaporates very slowly, leaving behind the calcite mineral. An incalculable number of drops must evaporate to create a large hanging formation.
