活石(Living rock)

欢迎来到土耳其卡帕多西亚的戈雷米，这是一个由火山岩组成的圆锥形结构点缀而成的地区，被称为胡德乌斯或仙女烟囱，通常出现在干燥炎热的地区。它们是由一层厚厚的火山灰经过数百万年的时间凝固成一种称为凝灰岩的软多孔岩石，然后被坚硬的玄武岩覆盖而形成的。表面的裂缝使风和雨逐渐冲走较软的底层，留下坚硬的玄武岩覆盖凝灰岩的高柱。其结果是这些不同寻常的，往往是美丽的形成，发现了整个地区。

Welcome to Göreme, in Cappadocia, Turkey, a region dotted with conical formations of volcanic rock known as hoodoos or fairy chimneys, typically found in dry, hot areas. They formed when a thick layer of volcanic ash solidified over millions of years into soft, porous rock called tuff that was then covered by hard basalt. Cracks in the surface allowed wind and rain to gradually wash away the softer bottom layer, leaving the hard basalt to cap tall columns of the tuff. The result is these unusual, often beautiful formations, that are found across the region.
