ICE BERRRG!
The largest Northern Hemisphere iceberg was encountered near Baffin island in 1882. It was 13 km long , 6 km wide and was about 65 feet above water. The mass of that iceberg was in excess of 9 billion tons!
The interior temperature of iceberg can be in the range of-15 to-20 C.
Why do icebergs look mostly white? Because of all the air bubbles trapped inside, reflecting white light!
Iceberg float because the density of ice is lower than the density of seawater.
