科學(xué)家宣布發(fā)現世界第八大洲

Kids are frequently taught that seven continents exist: Africa, Asia, Antarctica, Australia, Europe, North America, and South America.

孩子們經(jīng)常被教導世界存在7大洲：非洲、亞洲、南極洲、大洋洲、歐洲、北美洲和南美洲。

Geologists, who look at the rocks (and tend to ignore the humans), group Europe and Asia into a supercontinent — Eurasia — making for a total of six geologic continents.

地質(zhì)學(xué)家們通過(guò)觀(guān)察巖石（往往忽略了人類(lèi)），將歐洲和亞洲統稱(chēng)為“歐亞大陸”，這樣一來(lái)全球存在的地質(zhì)板塊一共就有6個(gè)了。

But according to a new study of Earth's crust, there's a seventh geologic continent called "Zealandia," and it has been hiding under our figurative noses for millennia.

但是根據對地殼的一項最新研究顯示，地球上存在著(zhù)第七個(gè)地質(zhì)板塊，名叫“西蘭蒂亞”，幾千年來(lái)它一直就藏在我們眼皮子底下。

The 11 researchers behind the study say that New Zealand and New Caledonia aren't merely island chains. Instead, they're both part of a single, 4.9 million-square-kilometer (1.89 million-square-mile) slab of continental crust that's distinct from Australia.

據參與該項研究的11名研究人員表示，新西蘭和新喀里多尼亞不僅僅只是島嶼鏈。它們是一個(gè)和大洋洲分離的、面積達490萬(wàn)平方公里（約合189萬(wàn)平方英里）的大陸板塊的一部分。

"This is not a sudden discovery, but a gradual realization; as recently as 10 years ago we would not have had the accumulated data or confidence in interpretation to write this paper," the researchers wrote in GSA Today, a journal of the Geological Society of America.

研究人員們在美國地質(zhì)協(xié)會(huì )雜志《GSA Today》上寫(xiě)道：“這并不是一個(gè)突然的發(fā)現，而是一個(gè)漸進(jìn)的過(guò)程。10年前我們沒(méi)有積累到這么多數據，所以沒(méi)有信心寫(xiě)這篇論文?！?/font>

Ten of the researchers work for institutions within the new continent; one works for a university in Australia.

在全部研究人員中，有10個(gè)人在這塊新大陸內的機構工作，另外一人則在澳大利亞某大學(xué)任職。

But other geologists are almost certain to accept the team's continent-sized conclusions, says Bruce Luyendyk, a geophysicist at the University of California at Santa Barbara, who wasn't involved in the study.

但是據加州大學(xué)圣芭芭拉分校的地球物理學(xué)家布魯斯·陸元迪克（他并沒(méi)有參與這項研究）表示，其他地質(zhì)學(xué)家幾乎肯定會(huì )接受該結論。

"These people here are A-list earth scientists," Luyendyk told Business Insider. "I think they've put together a solid collection of evidence that's really thorough. I don't see that there's going to be a lot of pushback, except maybe around the edges."

布魯斯向《Business Insider》透露：“參與這項研究的人都是一流的地球科學(xué)家。我認為他們確實(shí)收集了大量的證據。我不認為這項結論會(huì )受到太大的阻力，除了板塊的邊界可能有點(diǎn)問(wèn)題?！?/font>
