[Choose #1] Thats the reason ice floats and all life in water does not die when winter rolls in

[Choose #1] Water is most dense at 38 degrees. Water water temp below 38 degrees will float above a water temp of 38 degrees. Water starts to crystalize below 38 degrees and becomes more bouyant again.

[Choose #1] It’s a trick question. The key word is "You." So it’s true, "I" will never find water that freaking cold ANYWHERE! ;-)

[Choose #2] Water is crazy as the air when it comes to currents and what causes them. Thermoclines can come and go depending on this and the depth of the water.

[Choose #2] Currents can cause some strange situations. In still water I would say true, in reality I have seen warmer and colder below the 38 degree point.

[Choose #2] Not really sure, what I know from diving up here, is the lake "rolls over", in the fall/early winter. Through the winter the temp of the water does not really go below 4 degrees celcius at depth. I could have looked up the conversion but didn’t.

[Choose #2] Maybe in fresh water, it just feels colder going from warm to bone chilling :(

[Choose #2] I believe salt lowers the freezing point of water right?

[Choose #2] Water temperatures below 32 F can be found under ice in salt water
