Question

Which of the following describes a unique property of water that helps sustain marine life? It freezes upward from the bottom unlike other liquids that freeze downward from the top. It has a lower density in its solid state than it does in its liquid state. It shows changes in density at temperatures above 4 °C. It cools faster and heats up faster than most other liquids.

Answer 1

It has a lower density in its solid state than it does in its liquid state

Step-by-step explanation:

Here, we want to get the unique property of water that helps sustain marine life

As we know, the marine environment consists of several zones with different states. However, it is necessary that aquatic lives are supported in all zones.

In cases where we have a solid state of water, which is ice, aquatic organisms are expected to thrive. Now, the density of water matters in these states.

The density of water is lower in the solid state than in the liquid state, which is unusual for most other liquids. This unique property ensures the sustenance of aquatic lives
