Antarctica, which has its own distinct identity as the icy part of the earth, is separated from another huge iceberg ie iceberg, ice shelf. The size of this iceberg will be double that of the city of Chicago in the US. Scientists of NASA Space of American Space NASA have given this information.
On Wednesday, NASA Earth shared a tweet informing that a major part of the ice has broken and become iceberg. According to the tweet, the part from which this berg is broken is called Brunt Ice Shelf. This iceberg was on the verge of breaking up for more than two years. NASA said that the berg from the Brunt Ice Shelf is now finally broken.

According to NASA’s Earth Observatory website, the Iceberg named A-74 split in February. It was first spotted on GPS devices on February 26, 2021 and then confirmed by the Sentinel-1A Satellite of the European Space Agency. The image shared by NASA Earth has been taken with the help of the operational land imager of Satellite Landsat 8, which launched the Earth.
Let me tell you that two years ago, cracks had started coming in the ice sheet here, since then scientists had come to know about it. Concerns were also raised about the stability of the Brunt ice shelf from the cracks. Its size is 1270 square kilometers or double the size of Chicago.
Its first year in 2017, about one trillion tons of iceberg broke apart from Antarctica. This iceberg is the largest recorded till date. A 5800-square-kilometer section was separated from the Larsen C ice shelf, reducing Antarctica’s size by more than 12 percent.
