Map shows path of Iceberg A23a as it breaks away from Antarctica. NASA The iceberg, whichreportedlyweighs nearly one trillion metric tons, has been seen freely drifting beyond Antarctic waters toward the Southern Ocean. It is expected to be swept to an area known as "iceberg alley," ...
Such a catastrophe was ultimately averted when the iceberg broke up into smaller chunks — a possible endgame for A23a as well. But "an iceberg of this scale has the potential to survive for quite a long time in the Southern Ocean, even though it's much warme...
根据第三段“A23a is about 365 meters high, which kept it touching the bottom of the sea and stuck there for over 30 years. ”A23a 大概有365米高,这使得它能触及到海底并待在那里超过30年。可知,因为A23a的高度导致无法移动。故选A项。59. 细节理解题。根据第四段“The iceberg will leave ...

A23a will likely be ejected into what's called the Antarctic Circumpolar Current, which will put it on a path that has become known as "iceberg alley," the BBC reports. That is the same current of water that famed explorer Ernest Shackleton used in 1916 to make his storied escape fr...
根据文中“A23a could make its way farther north up toward South Africa, where it may become a danger to ships”和“ If it comes too close to the shore, it could cause inconvenience to the millions of seals, penguins, and seabirds living on the island.”可知,冰山运动可能导致的结果是会...
As A23a moves north and warms in the coming weeks, its melt rate will accelerate, and it'll be dumping more fresh water into the ocean daily than is consumed by the entire UK population. 在未来几周,随着 A23a 向北移动并逐渐处于更温暖的环境中,它的融化速度将会加快,融化造成其每天向海洋倾...
The world’s largest iceberg is on the move again after being stuck for 30 years in the Weddell Sea. A23a is 3900 square kilometres in area, making it more than twice the size of Greater London and more than four times the size of New York City. It is 400 metres thick and it once...
