False, life doesn't hinge on ice on bodies of water.True or false: insulation of bodies of water by floating ice allows life to exist on earth?
True! Although my understanding is that it is more the fact that ice floats then it acts as an insulator. Think of it this way, what would happen if lakes slowly began to freeze? If the ice where denser then water it would sink to the bottom, the slow build up of ice from bottom to top. Ice that forms on the top of lakes allows life to continue below it.





I can't honestly ever how ice works as an insulator for lakes, but I do know that since the lakes do not completely freeze, some form of heat must be reaching them. Hope this helps.





Edit: this all assumes that we came from seas etc, (which don't freeze do to the large amounts of solutes in them)
