Which of the following is not true of stalagmites and stalactites?
Answer Details
The statement that is not true of stalagmites and stalactites is that "stalacties are formed on the floor of limestone caves while stalagmites are formed on roofs of limestone caves." In reality, stalactites are formed from the ceiling of a cave, while stalagmites are formed from the ground. Stalactites form when water containing dissolved minerals drips from the ceiling of a cave and the minerals gradually build up over time to form a pointed, icicle-like structure. Stalagmites form when the same water drips onto the floor of the cave and builds up into a mound or column. Therefore, the correct option is the third one.
