Basically, something like 60ish miles or 100ish kilometers beneath the ground is the earth’s mantle and this mantle is full of super-hot magma.

基本上， 地下 60 英里或 100 公里左右的地方就是地幔，而地幔充满了超热岩浆。

Given all the factors that conspire to limit the height of mountains, for example, sinking into the earth's mantle, fractures, and erosion — I wouldn't bet on our tallest mountains getting too much taller than they already are.

综合所有共同限制山脉高度的因素，沉入地曼断裂和腐蚀，我打赌我们能有的最高山，比现在已经存在的山要高很多。
