地球上到处都有战壕，包括战争期间制造的人工战壕，但是我们有太平洋上的马里亚纳海沟，很少有人潜入其中，而且只有詹姆斯·卡梅隆的帮助。马里亚纳海沟的深度是10994 m10.994公里，所以如果地球的大小是一个台球，那么这个区域的深度就相当于320粒砂纸的深度球体没有凹坑或凸起，但地球有，这也是它不太圆的另一个原因。—格雷戈里

There are trenches throughout Earth, including manmade trenches made during wars, yet we have the Mariana Trench in the Pacific, which few people dived in and 1 unassisted (James Cameron).The depth of the Mariana Trench is 10,994 m(10.994 km), so if Earth were the size of a billiard ball, that area would be like the depth on 320 grit sandpaper.A sphere doesn't have pits or bumps, but Earth does, and that's another reason it's not quite round. - Gregory
