Montana here,
You are absolutely right, if solid water sunk we would be an ice planet,
with a thin surface of lizuid. A chemist once told me that if a little bit
of alcohol is added to liquid water it shrinks. Pretty odd - you add
something and it gets smaller. Water is certainly about the coolest
substance to explore. I am continually learning about it all the time.
