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. This causes ice to be less dense than liquid water, so it floats on the surface of the ocean in the Arctic, forming an insulating layer. Other properties like being a versatile solvent, cohesive behavior, and ability to moderate temperature are not directly related to the formation of this floating insulating layer.

Answer:

expansion upon freezing
