PLANET EARTH Mountains
Human beings venture into the highest parts of our planet at their peril（in danger）. Some might think that by climbing a great mountain they have somehow conquered it, but we can only be visitors here.
This is a frozen alien world. This is the other extreme - one of the lowest hottest places on Earth. It's over a hundred meters below the level of the sea. But here a mountain is in gestation（gestation 本身可以表示孕育的意思，这里意译为山脉的生长通常来说，因为河流等侵蚀作用，山脉不会无限生长）. Pools of sulphuric acid（硫酸） are indications that deep underground there are titanic（从泰坦尼克一次演变而来，表示巨大的） stirrings.
This is the Danakil Depression in Ethiopia（埃塞俄比亚的达纳基尔洼地）, lying within a colossal（巨大的） rent of the earth's surface where giant land masses are pulling away from one another. Lava（拉瓦河） rises to the surface through this crack in the crust（地壳的裂缝） creating a chain of young volcanoes.
