沙子看似不起眼,实际上包罗万象——它是由火山爆发、山体腐蚀、有机体死亡,甚至人造物分解后留下的残余物形成的。如果你像科学家那样用3D显微镜观察它的颜色、纹理、形状,便不难发现,每一粒沙都是一个千姿百态的世界!来自星星的沙西太平洋塞班岛是一个由珊瑚礁构成的岛屿,在其海边的细沙中,有无数形似星星的大沙粒!它们是由存 The seemingly insignificant, in fact, all-encompassing sand is formed by the remains of volcanic eruptions, mountain erosion, organism death, and even the decomposition of man-made things.
