stalactites. 钟乳石 Each drop leaves behind only a miniscule amount of calcite, 每滴水珠只会留下极少量的方解石微粒 but over time the process can produce some spectacular results. 但随着时间的推移 它们变成了最引人入胜的景观 If the water seeps though the ceiling quickly, 若是水从洞顶滴落的速度...

and they're still getting bigger 它们仍在不断扩大 as each year rainwater eats away a little more limestone. 因为每年雨水都会侵蚀掉少许石灰岩 But water in caves doesn't only erode. 可是洞里的水不光只是侵蚀 It also builds. 它们还能造景 This water is loaded with dissolved lime...
