Question

question 1-2
in the arctic, marine life depends on the formation of an insulating barrier that forms on top of the ocean. which of the following properties of water contributes to the formation of this layer?
versatile solvent
cohesive behavior
expansion upon freezing
ability to moderate temperature

Explanation:

Water expands when it freezes. In the Arctic, this causes ice to form on the surface of the ocean. Ice is less dense than liquid water and acts as an insulating barrier. The other properties listed do not directly contribute to the formation of this surface - insulating layer.

Answer:

expansion upon freezing
