Proof that mother nature is a cruel, mean, cold hearted, son of a bitch.
And when she is, she is doing it with pure unadulterated beauty.
It actually makes sense but it isn’t something I considered before. Normally with I think of saltwater in the ocean I don’t think of salinity changing so rapidly. In this case as ice forms the salinity increases (salt water has a lower freezing point), that salt water with a higher salinity is more dense and colder so it begins descending. The fact that water is colder, below the freezing point of the surrounding water, causes the surrounding water to freeze. Wash, Rinse, Repeat.
Remember that the next time someone says you should be cuddly with mother nature because frankly, she won’t cuddle you back. If she could she’d freeze your ass in place for the hell of it.
