Question

Why does ice stay at the top of oceans instead of sinking to the bottom? Ice is colder than liquid water. Ice is warmer than liquid water. Ice is more dense than liquid water. Ice is less dense than liquid water.

Answer 1

B. Ice is less dense than liquid water.

This is because when water freezes, its molecules spread apart into a specific arrangement that makes frozen water less dense than liquid water.

Answer 2

The correct answer is that ice is less dense than liquid water.

Step-by-step explanation:

In the case of water, that is, when the water becomes colder than 4 degree Celsius, water starts to expand and becomes less dense as it becomes cooler. As a consequence, at the time of freezing, the warm water sinks to the bottom, and the colder water floats to the top. Ultimately, the coldest water in the freezing conditions that have floated to the top of the water body, freezes to produce a layer of ice. Thus, as the water freezes to ice, the ice becomes substantially less dense in comparison to water and continues to float on the surface of the water body.
