Which lime deposit grows downward from the roof of a cave?
Answer and explanation
Correct answer: Stalactite
The governing concept is mineral deposition inside a limestone cave. Groundwater carrying dissolved calcium carbonate reaches the cave roof, and droplets lose carbon dioxide as they hang there; calcite is gradually deposited downward from the roof, forming a stalactite. A stalagmite grows upward from the floor, a pillar joins roof and floor, and a drumlin is glacial. Therefore option D is correct.
