Dunes rise over a kilometer high... 沙丘升高至超过一千米
The drying that started in a previous era 前一个时代♥开♥始的干旱
and a single immense land mass on the other, 在另一边形成了一个巨大的陆地
creating a vast ocean on one side of the world... 在世界的一边形成一片广阔的海洋
the volcanic eruptions turned it from a bottom-of-the-food-chain burrower... 火山喷发使它从食物链底端的挖洞者
...in a crust up to three kilometers deep. 表层厚达三千米
