Bodies of water, such as ponds, freeze from top to bottom, forming a floating sheet of ice. This can help aquatic organisms survive during cold winter months.
Which of the following statements explains why the ice floats on the surface of the pond?
Choose 1
The ice molecules have higher kinetic energy than the liquid water molecules, causing them to
float.
As water freezes, ionic bonds form between water molecules, preventing the ice from sinking
below the surface.
The crystalline structure of solid ice makes it less dense than liquid water.
The increased number of hydrogen bonds in ice compared to liquid water causes the water
molecules in ice to be closer together
