E) pressure is lowered and evaporation is possible

Question

Quizplus · Accepted Answer

In a cavern, pressure is lowered and evaporation is possible, which leads to the precipitation of lime from solution. This occurs because as the water reduces in volume due to evaporation, it becomes oversaturated with dissolved minerals, such as calcium carbonate, and is no longer able to hold them in solution. As a result, these minerals precipitate out of the solution and form deposits, such as stalactites and stalagmites.
