Question

Quizplus · Accepted Answer

Limestone is a sedimentary rock that is often composed of calcium carbonate, which is soluble in water containing carbon dioxide, creating the perfect environment for the formation of caves. Over time, acidic water dissolves the rock and can create large underground spaces known as caves. Sandstone, quartzite, and shale are not typically soluble in water and therefore do not commonly form caves.
