Which of the following properties of water help support thesurvival of aquatic life during these periods of time?A. the expansion of water as it freezes results in a solid layer that maintains thetemperature of the liquid water below the ice.B. the ability of water to act as a solvent when freezing allows the ice that forms to storenutrients for plants and animals..C. the polar nature of frozen water results in solid sheets of ice that form in deeper regionsof bodies of water.D. the high surface tension of water as it freezes allows ice to form on surface layers ofbodies of water.

Answer 1

The correct option is D. the high surface tension of water as it freezes allows ice to form on surface layers of bodies of water. This results in a top ice layer, while the bottom is cold but liquid, allowing cold adapted animals to thrive.
