On January 22, an iceberg(冰山) broke off from Antarctica's Brunt Ice Shelf. The iceberg,known as A81, covers an are a of about 1, 550square kilometers. That's about twice the size of New York City. The iceberg is about 152 meters thick. Though Antarctic a has been losing a lot ...
(2024 · 聊城模拟)On January 22.massive iceberg broke off from Antarctica's Brunt Ice Shelf. Scientists say the iceberg was expected to break off and the event isn't connected to climate change. But the size of the iceberg is hard to imagine.The iceberg, known as "A81", is extremely ...
Iceberg A68a, which was at one point the world's largest, was set on a collision course with a remote South Atlantic island last November, threatening the home of thousands of penguins and other wildlife, but broke into smaller chunks before it reached the island. That iceberg measured about...
Scientists have recently found that the deepest layers of the southwest Atlantic between Argentina and Antarcticaexhibit a long term heating trendat all sites measured. Thus, the Scotia Sea is much warmer than the Weddell Sea that abuts the Larsen ice shelf, and it is when Iceberg A68A entered...

“ghost islands”, were in fact icebergs. The icebergs broke off from glaciers on the Greenland mainland, covered with gravel and rock, and temporarily stranded on the bottom of the Arctic Ocean north of Greenland. According to Danish scientist Prof. René Forsberg (DTU Space, Technical ...
(Lake Agassiz) formed inCanadaover much of present-day Manitoba. When theice dambroke, an armada of icebergs was suddenly released into the North Atlantic. As the icebergs melted, they added so much fresh water at the surface that the normal winterconvectionprocesses were turned off in the ...
—In photos: Huge icebergs break off Antarctica Because the ice shelf that this berg calved from was already floating on water, the event won't directly impact sea levels. However, ice shelves help to slow the flow of glaciers and ice streams into the sea; so indirectly, the loss of pa...
“A76 and A74 are both just part of natural cycles on ice shelves that hadn't calved anything big for decades,” Laura Gerrish, a researcher at the British Antarctic Survey,wrote on Twitter. “It's important to monitor the frequency of all iceberg calving, but these are all expected for...
根据第一段On January 22,a massive iceberg broke off from Antarctica's Brunt Ice Shelf.(1月22日,一座巨大的冰山从南极洲的布伦特冰架上断裂)及全文可知,文章介绍了南极冰山的裂冰现象。科学家认为冰山断裂与气候变化无关,而是与冰山的大小息息相关。由此可知,A项"Massive Iceberg Breaks from Antarctica(巨大...
