Question

Quizplus · Accepted Answer

Limestone is a sedimentary rock that is easily soluble in water containing carbon dioxide, making it the most common rock type for the formation of caves by dissolution. Sandstone, granite, and slate are all more resistant to dissolution, and porous lava flows may provide cave-like spaces but are not formed by dissolution.
