Frozen water isn’t as dense as liquid water, so ice is bouyant. What you see above the surface of the water is just a fraction of what is hidden below.
Hmmm. Not sure you’re correct. Tell you what: in a while I’m going to make me an Old Fashioned, and I’ll let you know if the ice cubes float
I agree. However, that doesn't explain why the thing is round and why it hasn't melted since black absorbs heat and it should have melted.
I hope they will send some scientists or prospectors to bring back samples. They can then figure what caused the color, and approximately when that happened. Maybe they can backtrack the original location of the berg and make a big find of some sort.
ICE FLOATS IN YOUR DRINKS.....
