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

145. As it builds up
     随着它的积累
146. so the calcite forms decorations that hang from the ceiling -
     方解石形成了悬在洞顶上的装饰物
147. stalactites.
     钟乳石
148. 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
149. 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
150. If the water seeps though the ceiling quickly,
     若是水从洞顶滴落的速度较快
151. then the calcite is deposited on the floor of the cave
     方解石就会在洞穴地面上沉积
