As in the image above, the iceberg is a rectangular block with straight edges and flat surfaces.The ice is often made up of breakage from ice blocks, but in this case, it comes from the Larsen C ice shelf - also the ice sheet that created the 2,200 square-mile ice block billion billion tons last year.
'There are two types of ice: one that everyone envisions, like an iceberg that sank the Titanic, with triangles or prisms on the surface;another is called tabular iceberg, 'Kelly Brunt, a tape researcher at NASA and the University of Maryland, told Live Science.
Because the wind and the sea are still not abraded to the straight edge of the ice sheet, this ice sheet is probably only separated.It is about a mile wide and like many icebergs, only about 10% above the surface is visible.
