An Icebergs are those that float in open water, fragmented by glaciers or shelf ice, and float along the currents of the ocean, but are stabilized in the presence of shallow water or coastal areas en route. The shape of the iceberg A68a is like a finger pointing from a closed fist that was separated from the Larsen Ice Shelf of the West Antarctic Peninsula. The temperature of this iceberg has increased faster than any other part of the southern continent of the Earth. This further led to the separation of small icebergs, after which the remaining large portion was named A68a, which is almost equal to the area of Delhi. Let's know more about Iceberg A68a.
