The Great Lakes of the United States are often covered with a sheet of ice every winter. Which best explains why this ice does not sink to the bottom? Cold air temperatures attract the ice to the surface.

Ice is less dense than water.

Aquatic life buoys the ice.

Water currents prevent the ice from sinking.

i believe its because ice is less dense than water

The correct answer would be ice is less dense the ice.

Explanation:

The water has a unique property of expansion exceptionally. Water is normally dense at room temperature and cooling it down is leads to an increase in the density of water. It reaches its highest density at the temperature of 4° C but further cooling decreases its density. Ice is forming below 0° C from water thus it is less dense than water.

Thus, the correct answer is ice is less dense than water.
