Now, however, with the help of sophisticated computers,
然而現在憑借先進的計算機,
scientists have discovered what seem to be superplumes, more intense thunderstorms, if you will.
科學家們已經發(fā)現了似乎是超級地幔柱的存在, 如果你愿意的話，這會帶來更為猛烈的暴風雨。
The computers produced 3D images of the mantle that suggest the existence of a superplume under Africa
電腦制作的地幔3D圖像表明超級地幔柱可能位于非洲下面,
and possibly another one under the Pacific.
或者可能另一個位于太平洋。
Some scientists suggest that these superplumes may be responsible for the strange shape of the Hawaii-Emperor seamount chain on the floor of the Pacific Ocean.
一些科學家認為,這些超級地幔柱可能就是造成太平洋海底夏威夷-皇帝海山鏈之所以奇怪形狀的原因。
This long chain of undersea mountains, formed over time as the crust moved across a hot spot in the mantle,makes a sharp 45 degree turn around Midway Island.
當地殼通過地幔一處熱點,以45度轉身前往中途島時這條海底山脈的長鏈隨著時間的推移最終形成。
The scientists propose that these superplumes may be responsible for pushing the crustal plates almost to the point of making them reverse directions.
科學家們認為,這些超級地幔柱可能推動地殼板塊向某一點運動使它們扭轉方向。
