冰洞是迷人的自然景观。阳光透过不同质地的冰，形成了迷人的色彩组合，仿佛大自然在冰上的画作。我们都知道，冰一般是白色的，但是冰岛的冰洞则会呈现出蓝色或黑色。这是为什么呢？ 冰洞是如何形成的 夏季气温升高，部分冰川融化，水流在冰川内部流淌形成了通道。有时，水流向下冲刷会形成冰臼，但由于冰臼是竖直向下的，比较危险，不适合游客参观。 有些横向的冰洞会在冰臼的基础上形成，有些仅仅是水流通过裂缝并逐渐将其冲刷扩大所导致的。 融化的水一般会从冰川的边缘流出，形成一个宽大的洞穴入口。冬季温度下降，没有融水流过，隧道就变成了冰洞。...This website uses cookies to improve your experience while you navigate through the website.
