转动地球仪,我常常会不自觉地生发感叹:这个被70%海洋包裹的蓝色星球,是多么神奇!丰富的动植物,奇异的地质地貌,还有我们脚下这片大地上埋藏的多样而丰富的矿产资源,构成了我们人类的美丽家园!或许,对我们来说,最不陌生又最让我们为之困惑的,要数随处可见的石头和岩体了。岩体,是地球的骨骼,它们支撑着地球,它们把地球家园里的所有东西集聚在了一块。我们不知道它们来自何处,它们既平常又充满奥秘。人类 Rotating the globe, I often unconsciously sigh: this 70% ocean-bound blue planet is amazing! Rich flora and fauna, strange geology and geomorphology, as well as the diversity and abundance Of the mineral resources that make up the beautiful homeland of our people! Perhaps the most familiar and the most perplexed to us, perhaps, for us, are the stones and rock masses that can be found everywhere. The rock mass, the skeleton of the earth, supports the earth and brings together everything in the home of the Earth. We do not know where they come from, they are both ordinary and full of mysteries. Humanity
