a column is born. 便形成了石柱 Structures like these in North America's Carlsbad Cavern 北美洲卡尔斯巴德溶洞中的这些构造 can take many thousands of years to develop. 经历了数千年的形成过程 But sometimes the formations in a cave stop growing altogether. 但有时洞穴内的这些活动会完全停止...

and that creates stalagmites. 最后形成石笋 Variations in water flow and the air currents 水流和气流的变化 produce an infinite variety of forms, but all are created by the same process - 造就了千姿百态的溶洞地形 但它们的形成过程都是一样的 the slow deposition of dissolved limeston...

If the water seeps though the ceiling quickly, 若是水从洞顶滴落的速度较快 then the calcite is deposited on the floor of the cave 方解石就会在洞穴地面上沉积 and that creates stalagmites. 最后形成石笋 Variations in water flow and the air currents 水流和气流的变化 produce an infinit...

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较快 then the calci...

calcite. 方解石 As it builds up 随着它的积累 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 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 p...
